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 = 0.000000 years 86,400 × 0.000000 = 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 94,670.8560 s — a drift of 8,270.8560 s. That gap is the rounding, not the conversion.
