About Temperature Units

Celsius is used for weather and cooking almost everywhere except the United States, which uses Fahrenheit. Kelvin is the scientific absolute scale: 0 K is absolute zero (−273.15 °C). Handy reference points: water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level, and −40 is the same in both Celsius and Fahrenheit.
