Temperature

Celsius, Fahrenheit, and Kelvin

Edit any field; the others stay in sync.

°F = °C × 9/5 + 32  ·  °C = (°F − 32) × 5/9  ·  K = °C + 273.15

Absolute zero is 0 K, the same as −273.15 °C and −459.67 °F. It is the lower limit of the thermodynamic temperature scale: at 0 K a system cannot release any more heat by cooling.
