Kelvin to Fahrenheit
Convert kelvin to fahrenheit instantly with the formula and a quick reference table.
Quick answer: Formula: °F = (K − 273.15) × 9/5 + 32. For example, 0 K = -459.67 °F, and 100 K = -279.67 °F.
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).
