What is a degree Celsius?
The degree Celsius (°C) is the unit of temperature used for weather, cooking and medicine in almost every country. Water freezes at 0 °C and boils at 100 °C at sea level, and normal body temperature is about 37 °C.
A degree Celsius is exactly the same size as a kelvin, so the Celsius scale is simply the kelvin scale shifted by 273.15: 0 °C = 273.15 K. It is 1.8 times larger than a degree Fahrenheit.
What degrees Celsius are used for
- Weather forecasts and climate data worldwide
- Oven temperatures and cooking outside the US
- Body temperature and medicine
- Science and engineering alongside the kelvin

History of the degree Celsius
Anders Celsius proposed his centigrade scale in 1742 with 0 at the boiling point and 100 at the freezing point of water. It was inverted soon after his death, and in 1948 the scale was officially renamed "Celsius" in his honor. Since 2019 it has been defined through the kelvin.
