Kelvin to degrees Fahrenheit

1 kelvin in degrees Fahrenheit
1 K = -457.87 °F
°F = K × 9/5 − 459.67

To convert kelvin to degrees Fahrenheit, use °F = K × 9/5 − 459.67. 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 °F = K × 9/5 − 459.67. 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 degrees Fahrenheit are in one kelvin?
One kelvin equals -457.87 degrees Fahrenheit. °F = K × 9/5 − 459.67.
How do you convert kelvin to degrees Fahrenheit?
Use °F = K × 9/5 − 459.67. So 10 K is -441.67 °F.
