About degrees Celsius and kelvins

Degree Celsius (°C)

The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point at standard pressure; 0 °C equals 273.15 K. It is used for weather, cooking and science in most countries.

Kelvin (K)

The kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero and one kelvin step equals one degree Celsius step. It is used in physics, chemistry and engineering.
