Type a value in either box: the conversion between kilopascals (kPa) and psi (psi) updates instantly.
Good to know
Tire placards in Canada often show kPa: 220 kPa is about 31.9 psi and 240 kPa is about 34.8 psi.
How to convert kilopascals to psi
To convert kilopascals to psi, multiply the number of kilopascals by 0.1450377. To go the other way, multiply psi by 6.894757.
psi = kPa × 0.1450377
Worked examples
- 100 kPa = 14.50377 psi
- 220 kPa = 31.9083 psi
- 250 kPa = 36.25943 psi
- 101.325 kPa = 14.69595 psi

About the units
KPa (kPa)
The kilopascal (kPa) equals 1,000 pascals, the SI unit of pressure. It appears on tire placards in Canada, Australia and many car manuals.
PSI (psi)
Pounds per square inch (psi) is the pressure unit used for tires and compressors in the US and Canada. 1 psi is about 6.895 kPa.
