The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.

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 | 3 | +0.09925 |
| 1 decimal | 2.9 | −0.00075 |
| 2 decimals | 2.90 | −0.00075 |
Round trip: take 2.90 psi back the other way and you land on 19.9948 kPa — a drift of 0.0052 kPa. That gap is the rounding, not the conversion.
