Frequently Asked Questions

How do I convert degrees Fahrenheit to kelvin?

Use the formula K = (°F − 32) × 5/9 + 273.15. For example, 32 °F becomes 273.15 K. The converter above applies the same formula instantly for any value you type.

What are the reference points in Fahrenheit and Kelvin?

At standard pressure, water freezes at 32 °F and boils at 212 °F. In kelvin those same points are 273.15 K and 373.15 K. Normal body temperature, 37 °C, reads 310.15 K.

What is 32 degrees Fahrenheit in kelvin?

32 degrees Fahrenheit is 273.15 kelvin, using the formula K = (°F − 32) × 5/9 + 273.15. The converter above applies it instantly for any value, including negative temperatures.

Why does converting degrees Fahrenheit to kelvin need addition or subtraction?

Temperature scales do not share the same zero point, so a simple ratio is not enough — each formula combines the 9/5 (or 5/9) degree-size ratio with an offset. Kelvin is the exception that proves the rule: it starts at absolute zero (−273.15 °C), so Celsius-to-Kelvin only shifts by 273.15.
