Kilopascals to Pounds per square inch

1 kilopascal = 0.14504 pounds per square inch · 1 psi = 6.8948 kPa

1 kilopascal = 0.14504 pounds per square inch

How it’s calculated

psi = kPa × 0.1450377377

  • Multiply the value in kilopascals by 0.1450377377.
  • To go back, divide by 0.1450377377 (or multiply by 6.894757293).
  • 1 kPa = 0.1450377377 psi · 1 psi = 6.894757293 kPa

  1. Find the conversion factor

    By definition 1 kPa = 1000 Pa and 1 psi = 6894.75729316836 Pa, so 1 psi = 6.89475729316836 kPa. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); NIST SP 811 / Handbook 44.

  2. Multiply by the factor written as a fraction

    Put kPa in the denominator so it cancels, leaving psi.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.
