SI unit and Oil metric unit of temperature which measure 0 °C for the melting point of water and 100 °C for the boiling point of water at 1 atm pressure.
It is related to absolute temperature in SI unit and Oil metric unit as: T [°C ] = T [°K] - 273.16
It is related to °F in Imperial Unit and Oil field unit as: T [°C] = ( T [°F] - 32 )/1.8
