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 1.50 × 60.000000 = 90
1.50 hours as 1 hr 30 min
A decimal is the right form for a spreadsheet and the wrong one for almost everything else. Split into whole units, 1.50 hr is 1 hr 30 min — 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 | 90 | exact |
| 1 decimal | 90.0 | exact |
| 2 decimals | 90.00 | exact |
Round trip: take 90 min back the other way and you land on 1.5000 hr — a drift of 0.0000 hr. That gap is the rounding, not the conversion.
