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 second = 0.000278 hours 72,000 × 0.000278 = 20.000
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 (h) | Off by |
|---|---|---|
| Whole number | 20 | exact |
| 1 decimal | 20.0 | exact |
| 2 decimals | 20.00 | exact |
Round trip: take 20.000 h back the other way and you land on 72,000.0000 s — a drift of 0.0000 s. That gap is the rounding, not the conversion.
