About kelvins and degrees Celsius
The kelvin is the SI unit of temperature. 0 K is absolute zero, and one kelvin step equals one degree Celsius, so K = °C + 273.15.
On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea level. It is used for weather and cooking almost everywhere except the US.
