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 month = 0.083333 years 120 × 0.083333 = 10.000
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 (yr) | Off by |
|---|---|---|
| Whole number | 10 | exact |
| 1 decimal | 10.0 | exact |
| 2 decimals | 10.00 | exact |
Round trip: take 10.000 yr back the other way and you land on 120.0000 mo — a drift of 0.0000 mo. That gap is the rounding, not the conversion.
