About kelvins and degrees Fahrenheit
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 Fahrenheit scale water freezes at 32 °F and boils at 212 °F. It remains the everyday temperature scale in the United States.
