kPa to PSI Converter

Divide kilopascals by about 6.894757 to get psi (1 kPa ≈ 0.145 psi).

220 kPa = 31.9083023006 psi

Convert pounds per square inch to kilopascals instead

Formula

1 kPa = 0.1450377377 psi

pounds per square inch = kilopascals × 0.1450377377

Worked example

Convert 240 kilopascals to pounds per square inch

  1. Multiply by 0.1450377377
  2. 240 × 0.1450377377 = 34.8091

240 kPa = 34.8091 psi

Good to know

A tire placard showing 240 kPa means about 34.8 psi. Standard atmospheric pressure is 101.325 kPa, or 14.696 psi. Quick estimate: multiply kPa by 0.145.
