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 | 44 | +0.48868 |
| 1 decimal | 43.5 | −0.01132 |
| 2 decimals | 43.51 | −0.00132 |
Round trip: take 43.51 psi back the other way and you land on 299.9909 kPa — a drift of 0.0091 kPa. That gap is the rounding, not the conversion.
