PSI to kilopascals formula

kPa = psi × 6.894757293

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

Example: 32 psi × 6.894757293 = 220.632 kPa.

Reverse formula (kilopascals to pounds per square inch): psi = kPa ÷ 6.894757293. Example: 413.685 kPa ÷ 6.894757293 = 60 psi.

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

About PSI and kilopascals

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.

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

Frequently asked questions

1 pound per square inch equals how many kilopascals?

One pound per square inch equals 6.89476 kilopascals.

How do you convert pounds per square inch to kilopascals?

Multiply the number of pounds per square inch by 6.894757293. For example, 32 psi × 6.894757293 = 220.632 kPa.

What is 60 pounds per square inch in kilopascals?

60 psi is 413.685 kPa.

How much is 120 pounds per square inch in kilopascals?

120 pounds per square inch equals 827.371 kilopascals.

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

Divide by 6.894757293, or press the ⇄ swap button above. For example, 413.685 kPa ÷ 6.894757293 = 60 psi.

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.
