Convert Kilopascals to PSI (kPa to psi)
1 kPa = 0.145037738 psi. Convert kilopascals to PSI with the exact factor, a common-values table and a free converter.
Conversion factor
psi = kPa × 0.145037738
1 kPa = 0.145037738 psi
Multiply by 0.145037738 psi to go from kilopascals to PSI, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.

Frequently asked questions
How many PSI are in one kilopascal?
One kilopascal is 0.145037738 psi, so 100 kPa is 14.5037738 psi.
What is the formula to convert kilopascals to PSI?
psi = kPa × 0.145037738. Multiply the value in kilopascals by 0.145037738 to get PSI.
How do I convert PSI back to kilopascals?
kPa = psi × 6.89475729, so 1 psi is 6.89475729 kPa. The psi to kPa page carries the same table in that direction.
