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.

|---|---|---|
| Whole number | 400 | exact |
| 1 decimal | 400.0 | exact |
| 2 decimals | 400.00 | exact |
Round trip: take 400.0 cm back the other way and you land on 4.0000 m — a drift of 0.0000 m. That gap is the rounding, not the conversion.
