Absolute zero is the temperature at which a molecule has no kinetic energy. It is at #-273.15^o C#.


The other main temperature reading scale is Kelvin - not degrees, Kelvin.

A change in temperature of 1 Kelvin is the same as a change of 1 degree Celcius, however, the Kelvin scale is zeroed at absolute zero. Therefore, absolute zero is at #0K#.

Also, if you have the misfortune of having to deal with Fahrenheit, the value of absolute zero is #-459.67#.


The Rankine scale, which I didn't include because I've never heard of it, is to the Fahrenheit scale what Kelvin is the Celcius.

That is to say that it is zeroed on absolute zero, like Kelvin, but 1 unit on the Rankine scale is equal to one unit of the Fahrenheit scale.
