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 | 22 | +0.24434 |
| 1 decimal | 21.8 | +0.04434 |
| 2 decimals | 21.76 | +0.00434 |
Round trip: take 21.76 psi back the other way and you land on 150.0299 kPa — a drift of 0.0299 kPa. That gap is the rounding, not the conversion.
