About Kelvin and Celsius
Temperature scales describe thermal state. Celsius and Fahrenheit use different zero points and degree sizes, while kelvin is an absolute thermodynamic scale beginning at absolute zero. The kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero and one kelvin has the same interval size as one Celsius degree. Celsius is a temperature scale on which 0 °C equals 273.15 K and one Celsius degree has the same interval size as one kelvin.
Exact Conversion Relationship
K − 273.15 = °C
Apply K − 273.15 = °C: 0 K → -273.15 °C
