Fahrenheit to Kelvin
Convert fahrenheit to kelvin instantly with the formula and a quick reference table.
Quick answer: Formula: K = (°F − 32) × 5/9 + 273.15. For example, 0 °F = 255.37 K, and 100 °F = 310.93 K.
Good to know
- A quick estimate from °C to °F: double it and add 30. It is close for everyday weather.
- Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level. Normal body temperature is about 37 °C (98.6 °F).
