State
The kelvin is SI's unit of temperature; Celsius shares its degree size but places zero at water's freezing point, not absolute zero.
Show
A change of one degree Celsius equals one kelvin, but 0 °C is roughly 273 K, not 0 K.
Watch for
Kelvin values are never written with a degree symbol — a habit carried over from Celsius and Fahrenheit that is incorrect.
