In short
How many kelvin is -10 Fahrenheit?
-10 °F = 249.82 K. 1 Fahrenheit = 0.555556 kelvin, then + 255.3722222222222, so the working is -10 × 0.555556 + 255.3722 = 249.82.
The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 Fahrenheit = 0.555556 kelvin, then + 255.3722222222222 -10 × 0.555556 + 255.3722 = 249.82
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (K) | Off by |
|---|---|---|
| Whole number | 250 | +0.18333 |
| 1 decimal | 249.8 | −0.01667 |
| 2 decimals | 249.82 | +0.00333 |
Round trip: take 249.82 K back the other way and you land on -9.9940 °F — a drift of 0.0060 °F. That gap is the rounding, not the conversion.
