Temperature Information
Kelvin Scale

The Kelvin scale is an absolute thermodynamic temperature scale where 0 K represents absolute zero, the point at which all thermal motion ceases.

Celsius Scale

The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C (at standard atmospheric pressure).

Conversion Formula

Celsius = Kelvin - 273.15

Kelvin = Celsius + 273.15
