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
4 × 1,000.000000 = 4,000

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.
