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 42 × 60.000000 = 2,520

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.

|---|---|---|
| Whole number | 2,520 | exact |
| 1 decimal | 2,520.0 | exact |
| 2 decimals | 2,520.00 | exact |
Round trip: take 2,520 min back the other way and you land on 42.0000 hr — a drift of 0.0000 hr. That gap is the rounding, not the conversion.
