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 Celsius, then − 17.77777777777778 82 × 0.555556 − 17.7778 = 27.8
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 (°C) | Off by |
|---|---|---|
| Whole number | 28 | +0.22222 |
| 1 decimal | 27.8 | +0.02222 |
| 2 decimals | 27.78 | +0.00222 |
Round trip: take 27.8 °C back the other way and you land on 82.0400 °F — a drift of 0.0400 °F. That gap is the rounding, not the conversion.
