In short
How many pounds per square inch is 100 kilopascals?
100 kPa = 14.50 psi. 1 kilopascal = 0.145038 pounds per square inch, so the working is 100 × 0.145038 = 14.50.
The working
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 | 15 | +0.49623 |
| 1 decimal | 14.5 | −0.00377 |
| 2 decimals | 14.50 | −0.00377 |
Round trip: take 14.50 psi back the other way and you land on 99.9740 kPa — a drift of 0.0260 kPa. That gap is the rounding, not the conversion.
What 100 kPa looks like
100 kPa
Exactly one bar. The bar is defined as 100,000 pascals, so this conversion is the one place in pressure where a round number is exact.
101.33 kPa
One standard atmosphere, fixed at 101,325 pascals by the 10th General Conference on Weights and Measures in 1954.
Frequently asked questions
What is 100 kilopascals in pounds per square inch?
