Convert Fahrenheit to Kelvin
Degrees Fahrenheit to kelvin. Enter a value to convert, or use the Fahrenheit to Kelvin chart further down the page.
Degrees Fahrenheit and kelvin are measured on scales with different zero points, so the conversion needs a formula rather than a single factor.
How to convert Fahrenheit to Kelvin
Degrees Fahrenheit and kelvin use different zero points, so you cannot convert them with a single multiplication. Apply the formula K = (°F + 459.67) × 5/9 instead.
K = (°F + 459.67) × 5/9
Worked example
Convert 68 °F to kelvin:
68 °F = 293.15 K

What is a degree Fahrenheit?
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F. It remains the standard scale for weather and cooking in the United States.
What is a kelvin?
The kelvin is the SI base unit of temperature. It starts at absolute zero and uses the same degree size as Celsius, so 0 K equals −273.15 °C.
