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 millimeter = 0.001000 meters 1,000 × 0.001000 = 1.0000
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 (m) | Off by |
|---|---|---|
| Whole number | 1 | exact |
| 1 decimal | 1.0 | exact |
| 2 decimals | 1.00 | exact |
Round trip: take 1.0000 m back the other way and you land on 1,000.0000 mm — a drift of 0.0000 mm. That gap is the rounding, not the conversion.
