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 meter = 0.001000 kilometers 800 × 0.001000 = 0.8000
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 (km) | Off by |
|---|---|---|
| Whole number | 1 | +0.20000 |
| 1 decimal | 0.8 | exact |
| 2 decimals | 0.80 | exact |
Round trip: take 0.8000 km back the other way and you land on 800.0000 m — a drift of 0.0000 m. That gap is the rounding, not the conversion.
