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 (psi) | Off by |
|---|---|---|
| Whole number | 20 | −0.30528 |
| 1 decimal | 20.3 | −0.00528 |
| 2 decimals | 20.31 | +0.00472 |
Round trip: take 20.31 psi back the other way and you land on 140.0325 kPa — a drift of 0.0325 kPa. That gap is the rounding, not the conversion.
