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 (cm) | Off by |
|---|---|---|
| Whole number | 1 | −0.10000 |
| 1 decimal | 1.1 | exact |
| 2 decimals | 1.10 | exact |
Round trip: take 1.10 cm back the other way and you land on 11.0000 mm — a drift of 0.0000 mm. That gap is the rounding, not the conversion.
