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 | 0 | −0.19685 |
| 1 decimal | 0.2 | +0.00315 |
| 2 decimals | 0.20 | +0.00315 |
Round trip: take 0.20 in back the other way and you land on 5.0800 mm — a drift of 0.0800 mm. That gap is the rounding, not the conversion.
