How to Convert KPa to Psi

1 kPa = 0.145038 psi

Psi = KPa × 0.145038

Example: 1 kPa × 0.145038 = 0.14504 psi

Reverse Conversion

To convert psi back to kPa:

  • Remember, 1 psi equals 6.89476 kPa.
  • To convert 0.14504 psi to kPa, multiply 0.14504 x 6.89476, resulting in 1 kPa.

1 kPa is also equal to:

  • 1000 pascal
  • 0.01 bar
