# Degrees Fahrenheit to kelvin

**1 degree Fahrenheit in kelvin: 1 °F = 255.9278 K**

K = (°F + 459.67) × 5/9

To convert degrees Fahrenheit to kelvin, use K = (°F + 459.67) × 5/9. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is K = (°F + 459.67) × 5/9. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.

## Common questions

### How many kelvin are in one degree Fahrenheit?

One degree Fahrenheit equals 255.9278 kelvin. K = (°F + 459.67) × 5/9.

### How do you convert degrees Fahrenheit to kelvin?

Use K = (°F + 459.67) × 5/9. So 10 °F is 260.9278 K.

### How many degrees Fahrenheit are in one kelvin?

One kelvin equals -457.87 degrees Fahrenheit, which is the reverse of the conversion above.
