About this illustration

Analog thermometer showing the temperature 100 degrees Celsius. Red column fills up to 100°C on a scale from -10°C to 100°C. Indicates boiling point. For teaching temperature, measurement, integers, weather.

What is 100 °C in Fahrenheit?

This thermometer reads 100 °C. In Fahrenheit that is 212 °F, and on the Kelvin scale 373.15 K.

Celsius: 100 °C
Fahrenheit: 212 °F
Kelvin: 373.15 K
Conversion: (100 × 9) ÷ 5 + 32 = 212
Compared with freezing: 100 °C above

To convert Celsius to Fahrenheit, multiply by 9, divide by 5 and add 32: (100 × 9) ÷ 5 + 32 = 212, so 100 °C is 212 °F.
One hundred degrees Celsius is the boiling point of water at standard atmospheric pressure, the other fixed point of the Celsius scale. Water boils at a lower temperature higher up a mountain, where the air pressure is less.
On the Kelvin scale, used in science because it starts at absolute zero, the same temperature is 373.15 K — Kelvin degrees are the same size as Celsius degrees, so converting is just adding 273.15.
