Pounds per square inch to Kilopascals

1 pound per square inch = 6.8948 kilopascals · 1 kPa = 0.14504 psi

1 pound per square inch = 6.8948 kilopascals

How it’s calculated

kPa = psi × 6.894757293

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

  1. Find the conversion factor

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

  2. Multiply by the factor written as a fraction

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

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.

Answer: 6.8948 kPa
