How to use the Kelvin to Fahrenheit Converter
- Type a value in the Kelvin box. The fahrenheit result appears instantly.
- Going the other way? Type in the Fahrenheit box, or press the ⇄ swap button.
- Set the precision with the decimal places menu.
- Check the working in the step-by-step box, then press Copy result or click any row in the tables below.
Kelvin to fahrenheit formula
°F = (K − 273.15) × 9/5 + 32
- Subtract 273.15 to get degrees Celsius.
- Multiply by 9/5 (1.8).
- Add 32. The result is in degrees Fahrenheit.
Example: (300 − 273.15) × 1.8 + 32 = 80.33 °F.
Reverse formula: K = (°F − 32) × 5/9 + 273.15. Example: 68 °F → 293.15 K.
Shortcut: °F = K × 1.8 − 459.67.

About kelvin and fahrenheit
Kelvin (K). The kelvin is the SI unit of temperature. It starts at absolute zero (0 K = −273.15 °C), so it never goes negative and has no degree sign.
Fahrenheit (°F). The Fahrenheit scale puts water's freezing point at 32 °F and boiling point at 212 °F. It is used for weather and cooking in the US.
