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 | 6 | −0.11111 |
| 1 decimal | 6.1 | −0.01111 |
| 2 decimals | 6.11 | −0.00111 |
Round trip: take 6.1 °C back the other way and you land on 42.9800 °F — a drift of 0.0200 °F. That gap is the rounding, not the conversion.
