What is the SI unit of temperature?
The unit is the Kelvin. Zero on the Kelvin scale is the coldest
possible temperature, absolute zero. The scale increases by the
same degree intervals as the Celsius scale but since Kelvin starts
at absolute zero, the values are all higher. For example, it is
273.15 K when it is 0°C (Celsius). Kelvin "K" It is
KELVIN!!!!! Either Kelvin, or Celsius. Both are used
with the SI K degrees
