    How to Convert psi to Kilopascal

    • 1 psi = 6.894757293 kPa
    • 1 kPa = 0.1450377377 psi
    • Example: convert 15 psi to kPa: 15 psi = 15 × 6.894757293 kPa = 103.4213594 kPa

    Formula

    kPa = psi × 6.894757293168

    Derivation from SI units:

    • 1 psi = 1 lbf/in² = (0.45359237 kg × 9.80665 m/s²) ÷ (0.0254 m)² = 6894.757293168 Pa
    • 1 kPa = 10³ Pa
    • 1 psi = 6894.757293168 Pa ÷ 1000 Pa per kPa = 6.894757293168 kPa

    Both units are defined exactly, so the factor is exact. psi definition: psi; Kilopascal definition: kilopascal.

    Worked examples

    1. A tyre at 32 psi is inflated to 220.6322334 kPa.
      32 psi × 6.894757293 = 220.6322334 kPa
    2. A 100 psi compressed-air supply is 689.4757293 kPa.
      100 psi × 6.894757293 = 689.4757293 kPa
