About the units
Kelvin (K)
The kelvin is the SI unit of temperature. It starts at absolute zero, so 0 K is −273.15 °C, and one kelvin is the same size as one degree Celsius.
Degree Celsius (°C)
On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea level. Almost every country uses it for weather and cooking.
