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 day = 0.002738 years 1 × 0.002738 = 0.003
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 | 0 | −0.00274 |
| 1 decimal | 0.0 | −0.00274 |
| 2 decimals | 0.00 | −0.00274 |
Round trip: take 0.003 yr back the other way and you land on 1.0957 d — a drift of 0.0957 d. That gap is the rounding, not the conversion.
