About these units
Celsius puts 0° at the freezing point and 100° at the boiling point of water at sea level. Fahrenheit puts them at 32° and 212°, so one Celsius degree equals 1.8 Fahrenheit degrees. Kelvin uses Celsius-sized degrees but starts at absolute zero (−273.15 °C) and is written without a degree sign. Because the scales have different zero points, a temperature conversion adds or subtracts an offset as well as scaling.
FAQ
› How do I convert °F to K?
