How to convert degrees Fahrenheit to kelvins
Worked example: 70 °F ≈ 294.26 K
(70 + 459.67) × 5/9 ≈ 294.26 K
Rule: K = (°F + 459.67) × 5/9 — first add 459.67 to count from absolute zero (-459.67 °F = 0 K), then a step of 1 °F is a step of 5/9 K.
| °F | K | Usually |
|---|---|---|
| -459.67 °F | 0 K | absolute zero |
| 0 °F | 255.37 K | weather |
| 32 °F | 273.15 K | weather |
| 70 °F | 294.26 K | weather |
| 98.6 °F | 310.15 K | body temperature |
| 100 °F | 310.93 K | body temperature |
| 212 °F | 373.15 K | — |
| 574.5875 °F | 574.59 K | same number |

FAQ
What is the formula to convert Fahrenheit to Kelvin?
K = (°F + 459.67) × 5/9: add 459.67 to the degrees Fahrenheit, then multiply by 5/9. A change of 1 °F is a change of 5/9 K.
What is absolute zero in Fahrenheit?
-459.67 °F = 0 K — the lowest possible temperature; kelvins count from it.
At what temperature do Fahrenheit and Kelvin show the same number?
At 574.5875: 574.5875 °F = 574.5875 K — the only such point.
