Americans of Reddit, why don't you use Celsius or Kelvin, but instead use Fahrenheit, which needs this stupid formula to go from Celsius to Fahrenheit? Β°C to Β°F: Divide by 5, then multiply by 9, then add 32 Β°F to Β°C: Deduct 32, then multiply by 5, then divide by 9. Why?

Question for a Meteorologist

Why is -40 degrees the same in both Fahrenheit and Celsius?

I'm just a chef of 27 years. My scientific knowledge is very limited, besides the science of cooking haha. But Fahrenheit to Celsius is one of those things that is important to me when it comes to recipes. The other night I was just messing around with the formula, throwing around random numbers and stumbled across -40 degrees. Not only are there no videos on this, I can't even find one article or paper, or even a mention here.

The closer you get to -40 degrees, the smaller the gap between Fahrenheit and Celsius, and the further away in either direction the larger the gap grows.Β  What is so special about -40 Degrees?Β  Does this have something to do with absolute zero?

Yβall ever have wildly contradictory vibes with what youβre able to do?

Disclaimer: no money for diagnosis, but my dad has it and Iβm like, 95% sure I do too to a milder extent. For example:

I can tell time on an analog clock perfectly fine but can never tell you how many hours/minutes are between two times. 1:32PM - 5:56PM? No idea unless I can count the gaps between my fingers. Similarly if Iβm trying to figure out how much time has passed/still need to go when Iβm baking and using a digital clock... doesnβt work. I wish timers would count up instead of down.

I can tell my right from left from my own perspective (no idea from the other way), but god help me when I need to use a compass/need to remember east from west (unless itβs geography). I always have to be like Β«Β the sun rises in the east and sets in the westΒ Β». Or driving/remembering directions to pretty much anywhere until the 1000th time (and even then!)

I can do basic fractions when baking to add and convert measurements, but as soon as it goes on paper and is smaller than baking measurements my brain shorts out. I have no clue what to do with fractions.

I can add small numbers okay (when I can hold all of it in my head) and multiply numbers under 12 sometimes since iβve literally just rote memorized the tables (except the ones I forgot), but I canβt subtract well or do most division without a calculator or taking ungodly amounts of time (and still getting it wrong). But somehow I can understand discounts occasionally? BUT NOT FUCKING TIPPING? I know what 25% off means for a \$10 item, but wtf is 15% of a \$32.76 bill? Idk basically if itβs round numbers I might be able to do it because I intuitively understand baking fractions = percentages, but as soon as you leave very round small numbers or numbers used in baking Iβm like ?????? the fuck is this shit?

Canβt do much algebra and definitely not calculus but intuitive with basic statistics! Similarly, can sometimes briefly understand how to plug in formulas (NOT the math itself) for a few minutes and then itβs gone as soon as I stop (sometimes even during too lol). Thereβs some things that stick like PEMDAS, some basic algebra stuff, random formulas like y=mx+b, a^2 + b^2 = c^2... but I canβt always actually DO the formulas lol, sometimes I just happen to know what they are. Donβt talk to me about large LDCs, factorization, trig, circle of pi, calculus, calculating distance between two points, chemistry, physics, or whatever else. Itβs all magic.

Need help with a really easy project.

I know this is way too easy for a lot of you, but i'm really new at this and I was wondering if you all could help me out. Here is the project, it's in python btw, thanks in advance to anyone that decides to help.

You are going internationally over the Spring break. Think of a place you would like to visit. Some of you may want to visit Mexico, some to Canada, some to Europe, some to South America, and some to Asia. What all the countries and continents have in common though is that they all use degrees Celsius instead of Fahrenheit. It is currently summer still in the southern hemisphere where it may be hot and then winter in the northern hemisphere.

In this assignment you will ask for user input for the degrees Celsius. Next you will convert degrees Celsius into Fahrenheit and then print that out. Here is the formula to use for the conversion: F = (1.8 x C) + 32

You may get a decimal, so make sure to round the Fahrenheit to the nearest tenths location.

Next you will create a series of if, elif, and else statements based on the following:

if the degrees Fahrenheit is over 100, then put on a swim suit,

if the degrees Fahrenheit is less than 100, but greater than 75, you will wear a short sleeve shirt

if the degrees Fahrenheit is 75 or less, but greater than 60, you will wear a long sleeve shirt

if the degrees Fahrenheit is less than 60, but greater than 40, you will wear a sweater.

if the degrees Fahrenheit is less than 40, you will dress in snow gear.

Lastly, you will need to create an else statement, which gives an error message to the user that the amount they entered was invalid.

You will then make you that to print out the message for each if, elif, and else statement.

I (an American) sort of just came up with this when I was traveling in Europe. When talking about "human temperatures," I think in Fahrenheit, so it was useful to be able to convert temperatures quickly into the units I'm more familiar with.

I noticed a lot of people didn't bother actually doing the math to convert, probably because the formula they were taught involved fractions (specifically 9/5) which can be ugly to do in your head straightaway. So here's an easy way to approach it:

Take the temperature, in Celsius, and multiply it by 2.

Take 10% of that and subtract it from the number you got in the previous step.

This actually gets you an exact answer, but if you approximate your 10% you'll still get really close.

Example @ 15 Β°C:

15 Γ 2 = 30

10% of 30 = 3

30 - 3 = 27

27 + 32 = 59 Β°F

You can do the steps in reverse to go from Fahrenheit to Celsius, but using 10% no longer yields an exact answer. Really, you'd need to add 11.111..% which is no longer "easy to do in your head" - you can get REALLY close, but you'll have to do your 10% operation recursively.

EDIT: So the popular response is "Learn Celsius." Guys I'm an engineer - I "know" Celsius just fine. All of my formative experience with weather temperatures and the like happens to be in Fahrenheit and I still see temperature readouts in Β°F on a daily basis. My concept of temperature was forged using Fahrenheit by the American school system - that's not my fault. This is just a neat little trick for converting from one unit to another - the WHY doesn't matter.

YSK the easy mental math to convert km to miles and Celsius to Fahrenheit for Americans when metric units are used.

Edit: this information was meant for Americans to use, not for others to accommodate Americans.

The mathematical formula for kilometers to miles is 1.60934 km per mile (the 9.34 meters are negligible in almost all circumstances so I will go with 1.6 for my maths). Breaking it down to fractions, this is 8/5 km is 1 mile. This means for every kilometer, there are 5/8 of a mile.

An easy way to get 5/8 of any number is to divide it by 2, then add 25% of that number to it.

Example: 200km/2=100; 100/4=25; 100+25=125 miles.

The mathematical formula for Celsius to Fahrenheit is F=(9/5C)+32.

An easy way to get 9/5 of any number is by multiplying it by 2, then multiplying by .90 of that number (or subtracting 10%). From there, you just need to add 32 to get Fahrenheit.

Example: 25C*2=50; 50 * .90=45; 45+32=77F.

The descriptions are the same as the formulas but with simplified calculations which is easier to think of than trying to take 5/8 or 9/5 of a number during mental maths.

The inverse of km to miles is also easy by multiplying the miles by .80 (or just subtract one fifth) then multiply by 2. The inverse of Celsius to Fahrenheit is trickier because you need to subtract 32 from the Fahrenheit, then multiply that by 1/9 to be able to divide by 2 for the Celsius.

Is it Covid-19, or has it always been like this?

Good lord, I have had a deluge of whiny crybabies recently, and really always have, it just seems like more lately for some reason.

1. A few years ago, I did some corporate training for some side money with a recruiter, and was teaching phrasal verbs. I just gave the class a few examples and used "shut-up" (which everyone knows well) as and example, then explained that it's not really an abusing word, a bit rude, but just means be quite. Don't need the "up" part, but just shut the mouth upward. These people, WELL past the age of adulthood, acted like I jumped up on the table, pulled my pants down and took a dump right in front of them. Sour looking faces, suddenly no one wanted to talk or participate that day or the following. They paid for a 2 week block with an option every 2 weeks. They cancelled after the first 2 week block. Mental note: never use "shut up" in any circumstances, even when speaking to 45 year olds.
2. "Crazy Monkey." Yep, some brat went home after I taught a day at a winter camp and told his mom I said he was "crazy." Ugh......I just told the staff every kid in the class realizes that's a fun word, and the brat left off the "monkey" part, and we all just came to the conclusion that saying "Crazy monkey" to some kids, is the equivalent to jumping up on the table, pulling my pants down and taking a dump right in front of them. Mental note: no "shut up" for adults, no references to insanity with kids.
3. Another older private adult I teach 1:1, challenges nearly every grammar point, when he is corrected and wants a scientific answer as to why it's my way and not the way like he said. Since I'm not an English major, I can't really explain why an adjective goes before a noun in some cases, and not in others. "The adventurous man / The man is adventurous." Well why isn't it, "The man BE adventurous?" It goes on and on pretty much 4 or 5 times a session like that, and when I can't explain every situation, he just shakes his head, gets sassy, mutters something to himself in Korean like "Boy this foreigner doesn't know anything about his own language, why am I paying for this?" Teaching older stubborn men in the sciences like engineering is a disaster. They are in charge of people all day, and they don't like to be the subordinate, they need to control the classroom even though they know nothing. They need technical reasoning for everything.

Freemax Maxus 200W & 100W TC KITS - Innovation

Hi Reddit readers, In this review i take a look at the 200w & 100W Maxus TC Kits from Freemax. Both kits were supplied for the purpose of this review by Tina from Freemax.

Introduction

I remember about 4 years ago when Freemax first came to the attention of the vaping world they released a pretty handsome looking Resin finish dual 18650 device but the performance of their sub-ohm tanks and coil technology took off with a life all of their own so for obvious reasons Freemax for years concentrated on becoming global leaders when it comes to tanks and mesh coil technology.

Now that it seems they are that far ahead of the pack when it comes to their tanks and coils they have been able to start flexing their muscles in other directions and we have seen an avalanche of products from them in recent times which still incorporate their world beating coil heads at the forefront.

Here we have the first full size mods for 4 years from Freemax, the Maxus 200w and 100W which come paired with their 2 latest premium sub-ohm tanks. The Maxus mods boast very user friendly interfaces, full suite of the most popular modes, Type C USB and real innovation when it comes to battery polarity. The Maxus 100W allows the accommodation of a 21700, 20700 or 18650 with supplied adaptor which can be fitted either way and the Maxus 200W is a dual 18650 device which will allow any battery configuration including just one battery to be used either way at a reduced max wattage of 80w.

This is possibly the most innovation seen with mods for a considerable time, so let's crack on and give the Maxus 200w and 100w Kits a closer look!

Why Is A Level Physics Hard?

A Level Physics will be harder because assumptions and simplifications are gradually being removed to resemble real-world scenarios.

Compared to O Level, there is a steep increase in the learning curve.

This is only natural.

Having now graduated from the top 20% of the O Level cohort, the syllabus is now made much tougher to further differentiate among all of you.

## Simplification of Real World

Learning new concepts always start by trimming away the complexities.

For Physics, one of the items that complicate the maths will be friction.

So O Level Physics and to a certain extent A Level Physics always assumes a frictionless world.

Objects in motion, in the absence of friction, have to move forever.

But this comes as a cost as such assumptions does not gel very well with the real world.

On one hand you are told Physics aim to help you understand our physical world.

Yet on the other, you have to fight to resist the idea that you are forced to study something that appears to be blatantly incorrect.

Fake narratives like the famous Galileoβs experiment where he dropped a feather and cannonball simultaneously and found both to land on the ground at the same time confuses many Physics students.

βI thought there is supposed to be air resistance? How could this happen, when the terminal velocity of the feather is lower than that of a cannonball?β

## Gravitational Energy Formula

In A Level you will learn that GPE = mgh is nothing but a simplification when g is assumed to be constant.

Where gravitation field strengths changes in vast distances the GPE = mgh formula will break down and cannot be used.

## More Complex Concepts

As you progress in your education, more complicated concepts being introduced.

## Concept of Field

The concept of fields, such as the gravitational field, magnetic field, and the electric field is confusing because you cannot see them directly.

However, we can experience them either directly, through the effects of gravity or indirectly where you observe things move at distance from a force.

## Free-body Diagram

Learning to draw free-body diagrams can be a pain because you need to account for all the forces and their directions.

Students also find it hard to relate that frictional and normal contact force are c

How hot is the Nether?

[There is a lot of maths and science involved in this theory that some of you may not know (no offence), and if that is the case I am sorry for boring you. But in the end what matters is the answer we get, and how we can use it in the greater theory of Minecraft]

Hello again. After summing up what I think was the story of Minecraft, I thought I would look more into the environment of Minecraft, and the world that you, the player lives in. You could say that this mini theory tells us more about how strong these builders were. This will be the first of a series of posts that I will call The Physics of Minecraft.

Today I will be looking into how hot the Nether dimension really is.

The first thing I always do when answering a problem like this is giving myself a rough idea. I looked at the blocks found in the Nether, and used their melting points to give us a maximum. I looked at Nether Gold Ore (trust me Nether Gold is the same as normal gold, gold nuggets can be obtained from both ores, both identical, just different forms). The melting point of gold is 1064 degrees Celsius (or 1947.2 Fahrenheit). Gold is in its solid state in the Nether, so the average temperature in the Nether is less than 1064, and higher than 0 (it has to be higher than 0)

We can further narrow the bounds by looking at water. Water, when placed in the Nether, evaporates instantly. The Nether must have a temperature of at least 100 degrees Celsius (212 degrees Fahrenheit). So now the bounds are:

100 < T < 1064 (T is temperature).

That's the easy stuff.

We can actually work out the surface temperature by using the fact that the water evaporates instantly. We can use the thermal energy to work out the average temperature. You are now wondering why I went through the above if we could have worked it out straight away. I made boundaries so that I can compare my final value to it, to see whether the value is between the 100 and 1064.

So what is the thermal energy needed? Well the total energy is the energy required to heat the water to 100 plus the energy needed to evaporate it.

Total energy = Energy needed to raise temp. to 100 + Energy needed to evaporate water

E = mc delta(T) + mL

m = mass

c = specific heat capacity (energy required to raise 1kg of substance by 1 degrees Celsius

delta(T) = change in temperature

L = specific latent heat ( energy required to change state of 1kg of a substance - in this case it is the specific latent heat of vaporisation, because we a

Fahrenheit Celsius problem

The equation to convert from degrees Celsius to degrees Fahrenheit is F=1.8C+32, whereas a simpler estimate for this conversion is F=2C+30. By solving each of these equations for C, we can convert from degrees Fahrenheit to degrees Celsius.

If we write the rule of thumb estimate for Celsius as C=aF+b, what are the values of a and b?

If we write the the exact conversion formula as C=m(F+d), what are the values of m and d?

If the temperature in DC is 64 degrees Fahrenheit, what does the estimate give us for the temperature in degrees Celsius?

How many degrees off is this estimate from the true Celsius temperature?

Interesting Read: Putting those Tillandsia roots to work

The following was published in Bromeliad Society International's Journal, volume 67 issue 3 (Jul-Sep 2017). I found this really interesting and am considering setting up an experiment with some "extra" plants.

First-time membership in BSI is only \$15 for digital copies of the journal and often includes quite a bit of information about Tillandsia and Bromeliads, in general (including new species, taxonomy, horticulture, events, etc). Also included is a member list with contact info, so if you're trying to locate a "wish list" plant, it can be a great tool (I'm currently in-contact with a journal contributor and long-time member regarding how to locate less-available species).

BSI Journals include the following copyright statement:

Putting those Tillandsia roots to work!

By Jim Georgusis

Many Tillandsia species and hybrids are grown mounted on various surfaces, such as treefern slabs, poles, sea shells, coral, driftwood, cholla wood, and cork in many forms from wine corks to large fishing corks. Some are grown with no media or attachment at all, simply hanging on aluminum coils or wire, or lying on benches or wire mesh structures. Others are best grown in pots and baskets in media such as peat mixes that may have bark fines, orchid bark, perlite or vermiculite added. These plants are usually grown in clay, plastic, and even styrofoam pots with ample drainage. Some growers, due to their local rainfall and weather conditions, also grow their tillandsias in plastic net pots without any media, or they just place the plants in a PVC pipe cross section that has three holes drilled to receive either coated wire or monofilament fishing line, that enables plants to be hung at various levels wherever they are growing.

There are a few species and hybrids that are reluctant, or very poor at producing roots. My experience here in south Louisiana is that if you can expose the base of these plants - (after some of the small basal leaves have been carefully removed) - and apply a powder or liquid rooting hormone, you can get roots to initiate. Growing media components varies from grower to grower. This is dependent on the availa

How would you improve this script?

I'm not familiar with programming in AHK, though I've been using it for very simple scripting and for hotkey replacements for years. Recently I decided to write a simple utility script to convert a user's input value of Celsius β Fahrenheit and Fahrenheit β Celsius temperatures.

UPDATE: Solved! as explained in the comments 9/5 truncates to 1 instead of 1.8 because its integer division. solution would be to use 9.0/5.0

Hey I am writing a program that takes a degree in Celsius and converts it to Fahrenheit.

The formula the teacher gave me is F = (9/5) * C + 32;

Here is my code:

Here is my result when I enter 20 for degree in Celsius:

https://preview.redd.it/ypy6nmengwr41.png?width=246&format=png&auto=webp&s=fd28410f017f80e880dbab9fb4c9f1266e0ddc40

Its supposed to return 68 and not 52.

I figured that the program is ignoring (9/5) because when I enter 0 I get 32. So I am thinking its just adding the degree in Celsius and 32.

I used 1.8 in place of (9/5) and got the correct answer (68)

I also used a different equation I found online (celsius * 9) / 5 + 32 and that also gave me the correct answer 68.

so my question/ what I don't understand is why in the equation (9/5) * celsius + 32 the "(9/5)" part is being ignored?

Am I missing something completely obvious here?

Thanks for taking the time to read this!

LPT: To ballpark Celsius to Fahrenheit

When someone is talking and says something like it was hot, it was 30Β°C (86Β°F). This formula can get you close to the fahrenheit equivalent. Degrees celsius times two, plus thirty two equals ballpark fahrenheit this is a ballpark formula, best for mental math

(CΒ°x2)+32=

actual formula (CΒ°x9/5)+32=

Examples:

A. (5x2)+32=42

A. (5Β Γ 9/5) + 32 = 41Β°F

B. (21x2)+32=74

B. (21Γ 9/5) + 32 = 69.8Β°F

ELI5: What's the logic behind the wind chill formula?

The wind chill formula in Β°F :

``````Wind chill = 35.74 + 0.6215T β 35.75 (V^0.16) + 0.4275T (V^0.16)

T = Temperature in degrees Fahrenheit
V = Wind velocity in miles per hour
``````

The wind chill formula in Β°C :

``````Wind chill = 13.12 + 0.6215T β 11.37 (V^0.16) + 0.3965T (V^0.16)

T = Temperature in degrees Celsius
V = Wind velocity in kilometers per hour
``````

Although I've found posts on this sub that relate to how wind chill works, the answers given on the topic usually only say that there's a math formula people use, or why the wind chill phenomenon exists in the first place.

What I'm mostly looking for is an explanation as to why these numbers were picked to represent wind chill. What's the significance behind each number in the equation, if there is any? Or was the equation originally created in a more subjective fashion?

Guns don't get enough appreciation. Part 5 plasma rifle.

Hello! In this part, I would like to talk about one of the most unusual weapons in doomniverse, the plasma rifle. Before I start I should warn you, there is going to be quite a lot of physics stuff in this one so if you are afraid of learning new things you better off clicking away right now or just skipping to the conclusion. I will give you

You are still here? You have my respect, now let's dive into SCIENCE!

Basic power

To understand how powerful a gun is you need to understand how powerful is the bullet, or, in this case, the sphere of plasma. Since it's mostly heat weapon we need to find out how hot plasma is and how much heat does it have. Now, I would assume you have two questions:

Isn't temperature and heat the same thing?

And

Do we really need both?

Well, let me answer those questions.

--temperature vs heat

Temperature is the average kinetic energy of atoms. Basically how hot something is(big surprise!).

Heat is the sum of the kinetic energy of all atoms. Basically how much hotness something holds.

--Do we need both?

Yes. If something is very hot it doesn't mean it will burn you. For example, if you are cutting metal with a grinder there's going to be a lot of sparkles flying around, those sparkles are the peace of very hot metal, we are talking hundreds of degrees hot but if one lands on you it most likely wouldn't burn you, why? Well because it's very small and doesn't have a lot of heat, and vice versa, if something has a lot of heat but it's big it wouldn't be hot. That's why we need both of those values, we could make do with only one of them (especially if it's heat) but it wouldn't be as informative.

So, with all that out of the way, how do we find those values? Well, we just google the minimum temperature of the plasma, don't we? No, it's a bit more complicated, first, we need to understand what plasma actually is.

What is plasma?

Do you remember how your science teacher told you that there are 3 states of matter? This is not true, there is more, and plasma is one of them. However, it's completely different:

https://cdn.mos.cms.futurecdn.net/QsXPcrxs6m22C6cFMtqS6T-650-80.jpg

As you can see in solids atoms are sticking together in some shape, in liquids atoms are freer and don't have a strict shape but they are still attracted to each other and have a fixed volume, in gases atoms don't care about each other, they are just floating around without any shape or volume. All that happe

Still working out some math issues (small problems), for discharge rate but this is my Tasker (to) klwp broadcast for battery charging animation, discharge & charge times, temperature in both Celsius and Fahrenheit & more, almost everything is in the task but I am not broadcasting everything at the moment, but can be easy to add, it back if you planned on using all that can be broadcast.

It was originally u/Crashoverride93 profile import but I had a few phone models that had issues with it, adjusted what worked for me,

Kustom Klwp kodes I use

(custom animation formula inside multiple komponents)

\$if(bi(source)!=battery&gv(tasbat)>=800,1,r)\$

(the 800 is mAh that I have multiple komponents each having a different amount starting from "200" up to "1800" so more mAh you have more animations, you can also increase animation speed)

Freemax Maxus 200W & 100W TC KITS - Innovation

Hi Reddit readers, In this review i take a look at the 200w & 100W Maxus TC Kits from Freemax. Both kits were supplied for the purpose of this review by Tina from Freemax.

Introduction

I remember about 4 years ago when Freemax first came to the attention of the vaping world they released a pretty handsome looking Resin finish dual 18650 device but the performance of their sub-ohm tanks and coil technology took off with a life all of their own so for obvious reasons Freemax for years concentrated on becoming global leaders when it comes to tanks and mesh coil technology.

Now that it seems they are that far ahead of the pack when it comes to their tanks and coils they have been able to start flexing their muscles in other directions and we have seen an avalanche of products from them in recent times which still incorporate their world beating coil heads at the forefront.

Here we have the first full size mods for 4 years from Freemax, the Maxus 200w and 100W which come paired with their 2 latest premium sub-ohm tanks. The Maxus mods boast very user friendly interfaces, full suite of the most popular modes, Type C USB and real innovation when it comes to battery polarity. The Maxus 100W allows the accommodation of a 21700, 20700 or 18650 with supplied adaptor which can be fitted either way and the Maxus 200W is a dual 18650 device which will allow any battery configuration including just one battery to be used either way at a reduced max wattage of 80w.

This is possibly the most innovation seen with mods for a considerable time, so let's crack on and give the Maxus 200w and 100w Kits a closer look!

[Review] Freemax Maxus 100W Kit W/Fireluke 3 subohm tank

FREEMAX MAXUS 100W KIT W/FIRELUKE 3 TANK

This kit was sent to me from Freemax for the purpose of this review. It's a single battery mod that can run on an 18650, or a single 20700/21700. The tank is the Fireluke 3, successor to the Fireluke 2 and Fireluke M(esh) tanks. They've done some pretty cool things with the mod, and the tank will have a whole new lineup of SS904L Mesh coils. I've also reviewed this kit's big brother the Maxus 200W kit in case you're interested in that. I'll try to go over this one the best I can.

.

The kit includes-

• 1x MAXUS 100W Mod

• 1x Fireluke 3 Tank

• 1x 0.15ohm 904L M1 Mesh Coil

• 1x 0.2ohm 904L M2 Mesh Coil

• 1x 5mL Replacement Glass

• 1x Extra O-Ring

• 1x Type-C USB Cable

• 1x Warning Card

• 1x Warranty Card

• 1x User Manual.

.

.

The Maxus 100W mod-

The mod is all black with some minor branding on one side, and a side battery cover on the other. The battery cover is held on by magnets and it doesn't move once secured. On the outside of battery door is some decorative resin. Depending on which version you get, there'll be two different colored resins on your door. Mines Yellow or Gold on top with Blue on the bottom.. The screen is on the side and displays the pertinent information. The 510 connector is solid and is screwed down by two torx bit screws.

This mod has an interesting feature. It's called SmartLoad technology and Freemax is the first to do it. The mod doesn't care which way you put your battery in. You can put the cell in either way, and the mod will just work.

To turn the mod on and off is the industry standard 5 clicks. To enter the mods menu system click the fire button 3 times. [In the menu you can select MODE ; SET ; INFo ; or EXIT.](https://www.freemaxvape.com/wp-content/uploads/2020/06/%E5
