Convert PSI to Kilopascals (psi to kPa)
1 psi = 6.89475729 kPa. Convert PSI to kilopascals with the exact factor, a common-values table and a free converter.
Conversion factor
kPa = psi × 6.89475729
1 psi = 6.89475729 kPa
Multiply by 6.89475729 kPa to go from PSI to kilopascals, 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 kilopascals are in one PSI?
One PSI is 6.89475729 kPa, so 100 psi is 689.475729 kPa.
What is the formula to convert PSI to kilopascals?
kPa = psi × 6.89475729. Multiply the value in PSI by 6.89475729 to get kilopascals.
How do I convert kilopascals back to PSI?
psi = kPa × 0.145037738, so 1 kPa is 0.145037738 psi. The kPa to psi page carries the same table in that direction.
