echo-at-the-pond:

I wish my chem teacher would have explained it like this cause then I would have understood chem.

/transcript: ask on top of the video reads “Why do we have 3 different temperature measurements (K, F and C)”

person talking in a muffled voice because they are wearing a mask:

“That’s because all of these three different scales are measuring temperature in reference to a different thing.

The Kelvin scale sets 0 at absolute 0, you can’t get any colder. 0 is as cold as it gets and everything else is more heat than that.

Celsius is measuring in reference to water. Water freezes at 0 and it boils at a hundred. Everything else in the middle is where liquid water can exist.

Finally we have Fahrenheit. Fahrenheit is measured in relation to saftey to human beings. 0°F is when you start risking serious damage to yourself without special insulating equipment. And 100°F is when you start risking serious damage to yourself without special cooling equipment.

So yeah it’s that simple. Fahrenheit is measured in relation to humans, Celsius is in relation to water and Kelvin is measured in relation to the fundamental laws of our universe.” /end of transcript
