kPa to psi converter
1 kPa = 0.145038 psi
And 1 psi = 6.89476 kPa. Kilopascal to pounds per square inch.
Formula
psi = kPa × 0.145038
A reading of 15 kPa is 15 × 0.145038 = 2.17557 psi.

About these units
kPa (kilopascal): Common for HVAC, building ventilation and low-pressure gas work.
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
