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 8 × 0.555556 − 17.7778 = -13.3
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 | -13 | +0.33333 |
| 1 decimal | -13.3 | +0.03333 |
| 2 decimals | -13.33 | +0.00333 |
Round trip: take -13.3 °C back the other way and you land on 8.0600 °F — a drift of 0.0600 °F. That gap is the rounding, not the conversion.
