Celsius temperature	degree Celsius	C

Celsius temperature t is defined as the difference t = T-To between the two thermodynamic temperatures T and To where To = 273.15 K. An interval of or difference in temperature may be expressed either in kelvins or in degrees Celsius. The unit of 'degree Celsius' is equal to the unit 'kelvin'.
