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 (mph) | Off by |
|---|---|---|
| Whole number | 2 | −0.30156 |
| 1 decimal | 2.3 | −0.00156 |
| 2 decimals | 2.30 | −0.00156 |
Round trip: take 2.30 mph back the other way and you land on 1.9986 kn — a drift of 0.0014 kn. That gap is the rounding, not the conversion.
