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 kilometer = 1,000.000000 meters 21.50 × 1,000.000000 = 21,500
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 | 21,500 | exact |
| 1 decimal | 21,500.0 | exact |
