Kilopascals to PSI formula

psi = kPa ÷ 6.894757293

Take the value in kilopascals.
Divide it by 6.894757293 (the number of kilopascals in one pound per square inch).

Example: 220 kPa ÷ 6.894757293 = 31.9083 psi.

Reverse formula (pounds per square inch to kilopascals): kPa = psi × 6.894757293. Example: 36.2594 psi × 6.894757293 = 250 kPa.

Quick mental estimate: divide by about 6.9. For exact answers use the converter above.

About kilopascals and PSI

Kilopascals (kPa). The kilopascal is 1,000 pascals, the SI pressure unit. Tyre pressures are often printed in kPa outside the US.

PSI (psi). Pounds per square inch (psi) is a US customary pressure unit, used for tyre pressure, air compressors and plumbing. One psi is about 6,894.76 pascals.

Frequently asked questions

How many pounds per square inch are in a kilopascal?

One kilopascal equals 0.145038 pounds per square inch. Looking at it the other way, one pound per square inch is 6.89476 kilopascals.

How do you convert kilopascals to pounds per square inch?

Divide the number of kilopascals by 6.894757293. For example, 220 kPa ÷ 6.894757293 = 31.9083 psi.

What is 250 kilopascals in pounds per square inch?

250 kPa is 36.2594 psi.

How much is 500 kilopascals in pounds per square inch?

500 kilopascals equals 72.5189 pounds per square inch.

How do I convert pounds per square inch back to kilopascals?

Multiply by 6.894757293, or press the ⇄ swap button above. For example, 36.2594 psi × 6.894757293 = 250 kPa.

What is the difference between psi and psig?

psig is gauge pressure (above the surrounding air), which is what tyre gauges show; psia is absolute pressure. Atmospheric pressure at sea level is about 14.7 psi, 1.013 bar or 101.3 kPa.
