What is the Celsius equivalent of 100 K?
The difference between the Celsius scale and the Kelvin scale is where they start - Celsius has value 0 at the freezing point of water and Kelvin has value 0 at absolute zero, i.e. the coldest possible temperature possible (at least, that was the idea. Absolute zero has been adjusted a few times to reflect newer "lowest" temperatures science has found). The steps in the two scales are the same, and so the conversion here consists of adding/subtracting a fixed value. Currently, this value is
