Learn about the different temperature scales, boiling points, freezing points, and how to convert between Celsius, Fahrenheit, and Kelvin.
Thanks for stopping by, this is 2 Minute Classroom and today we are talking about temperature scales and how to convert between them.
First, allow’s introduce the scales and then I’ll talk about how to convert between them.
Celsius or centigrade is used in countries that use the metric system. Water freezes at 0 °C and boils at 100 °C.
On the fahrenheit scale, water freezes at 32 °F and boils at 212 °F.
The third and finale scale is the Kelvin scale, it is related the celsius scale but shifted by 273. So water freezes at 273 K and boils at 373 K. The Kelvin scale is based on absolute zero. This is the lowest temperature that is theoretically possible and puts atoms at their lowest energy state. So absolute zero is 0 K which is approximately -273 °C and -459 °F. Cute chilly.
Converting between celsius and Kelvin is simple, because a 1 degree movement on the Celsius scale is equal to 1 on the Kelvin, there is just a difference 273 between the temperatures. So simply take the celsius temperature and add 273 to obtain kelvin.
Converting between celsius and fahrenheit is a tiny trickier, because the degrees are not equivalent. Luckily, there is a easy equation. Allow’s convert 18 °C into fahrenheit. First, multiply 18 by 9/5 and then add 32, which gives you 64.4 °F.
Actually lets go the another idea and convert 18 °F into degrees celsius. The equation looks like this. We first need to subtract 32, then multiply the effects by 5/9. Giving us -7.8 °C.
If you are ever unsure if you are using the equation correctly, you can usually check by converting between the boiling points of every temperature.
I hope that supports you understand a tiny more about the temperature scales and how to convert between them. I would love to hear your questions and comment, so throw them below, and don’t forget to watch my another videos.
I’ll catch you next time.
*I just wanted to claim the person drawing at the beginning looked like something from “Allow Me Explain Studios”*
I think their r 4 kind of scale
Can u please solve this: http://prntscr.com/mb7677
I just wanted to claim I'm impressed you've kept up with the uploading each week for so long. If more of these videos happened to be relevant to my college courses I'd watch more but I'm still glad to see them pop up each week. Also congrats on 5k subs. I know last year you expected to be at 10k by actually, but I think you're doing nice
Thanks for supporting me learn!
