The short answer
How many Fahrenheit is 42 Celsius?
42 °C = 107.6 °F. 1 Celsius = 1.800000 Fahrenheit, then + 32, so the working is 42 × 1.800000 + 32.0000 = 107.6.
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 Celsius = 1.800000 Fahrenheit, then + 32 42 × 1.800000 + 32.0000 = 107.6
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 (°F) | Off by |
|---|---|---|
| Whole number | 108 | +0.40000 |
| 1 decimal | 107.6 | −0.00000 |
| 2 decimals | 107.60 | −0.00000 |
Round trip: take 107.6 °F back the other way and you land on 42.0000 °C — a drift of 0.0000 °C. That gap is the rounding, not the conversion.
