Unit converter
PSI to kilopascals.
Convert psi to kPa and kPa to psi. Type in either box and the other follows. A tyre gauge in psi against a handbook in kilopascals — multiply by 6.895.
| psi | kPa |
|---|---|
| 10 psi | 68.9476 kPa |
| 20 psi | 137.895 kPa |
| 28 psi | 193.053 kPa |
| 30 psi | 206.843 kPa |
| 32 psi | 220.632 kPa |
| 35 psi | 241.317 kPa |
| 40 psi | 275.79 kPa |
| 50 psi | 344.738 kPa |
| 80 psi | 551.581 kPa |
| 100 psi | 689.476 kPa |
- Conversion goes through Pa in both directions, so neither figure is rounded on the way.
Definitions
- The pound per square inch is exactly 6894.757 293 Pa. UK and US tyre gauges are still marked in it.
- The kilopascal is 1000 pascals. Tyre placards in metric countries are usually printed in kPa or bar.
- This conversion is exact by definition. 1 psi = 6.894757293 kPa.
- Pressure is converted through Pa.
How it works
One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.
The value passes through Pa, the unit every other pressure unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general pressure converter always agree.
Display precision sets a maximum number of significant figures and trims trailing zeroes, so it changes what you see and never what was calculated. The editable box always holds a plain number at full working precision, so you can carry on from either side.
Common questions this answers: how many kilopascals in a pound per square inch (6.89476), how many pounds per square inch in a kilopascal (0.145038), and what 32 psi is in kilopascals (220.632 kPa).
