What is a Kelvin?

In: Temperature [Edit categories]

Answer:

A Kelvin is the basic unit of temperature in the SI (metric) system. Its symbol is K.

It has the same size as one degree Celsius, but zero on the Kelvin scale is absolute zero, the lowest possible temperature, at which atomic movement would stop.

On the Celsius scale, absolute zero (0 K) is about -273.16 ^oC.
