How to Convert KPa to Psi

1 kPa = 0.145038 psi

Psi = KPa × 0.145038

Example: 18 kPa × 0.145038 = 2.6107 psi

Reverse Conversion

To convert psi back to kPa:

  • Remember, 1 psi equals 6.89476 kPa.
  • To convert 2.6107 psi to kPa, multiply 2.6107 x 6.89476, resulting in 18 kPa.

18 kPa is also equal to:

  • 18000 pascal
  • 0.18 bar
About these units

KPa: SI-derived pressure unit equal to 1,000 pascals (10³ Pa).

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.
