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 inch = 2.540000 centimeters 13 × 2.540000 = 33.02
13 inches as 1 ft 1 in
A decimal is the right form for a spreadsheet and the wrong one for almost everything else. Split into whole units, 13 in is 1 ft 1 in — the reading you would actually give someone, and the one a tape measure, a scale, or a timetable is marked in.
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 | 33 | −0.02000 |

Round trip: take 33.02 cm back the other way and you land on 13.0000 in — a drift of 0.0000 in. That gap is the rounding, not the conversion.
