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 = 3,600.000000 seconds 0.25 × 3,600.000000 = 900
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 (s) | Off by |
|---|---|---|
| Whole number | 900 | exact |
| 1 decimal | 900.0 | exact |
| 2 decimals | 900.00 | exact |
Round trip: take 900 s back the other way and you land on 0.2500 h — a drift of 0.0000 h. That gap is the rounding, not the conversion.
