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 79 × 0.555556 − 17.7778 = 26.1
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 | 26 | −0.11111 |
| 1 decimal | 26.1 | −0.01111 |
| 2 decimals | 26.11 | −0.00111 |
Round trip: take 26.1 °C back the other way and you land on 78.9800 °F — a drift of 0.0200 °F. That gap is the rounding, not the conversion.
