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 hour = 60.000000 minutes 18 × 60.000000 = 1,080
18 hours as 18 hr
A decimal is the right form for a spreadsheet and the wrong one for almost everything else. Split into whole units, 18 hr is 18 hr — 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 (min) | Off by |
|---|---|---|
| Whole number | 1,080 | exact |
| 1 decimal | 1,080.0 | exact |
| 2 decimals | 1,080.00 | exact |
Round trip: take 1,080 min back the other way and you land on 18.0000 hr — a drift of 0.0000 hr. That gap is the rounding, not the conversion.
