Illustration of standard atmospheric pressure
13.1 psi (90.0 kPa) is comparable to standard atmospheric pressure at sea level (101.325 kPa).

Did you know? Standard atmosphere (1 atm) is 101.325 kPa.

Sea-level atmospheric pressure is 101.325 kPa = 14.696 psi = 760 mmHg = 1 atm exactly.

How to Convert KPa to Psi

1 kPa = 0.145038 psi

Psi = KPa × 0.145038

Example: 90 kPa × 0.145038 = 13.053 psi

Reverse Conversion

To convert psi back to kPa:

  • Remember, 1 psi equals 6.89476 kPa.
  • To convert 13.053 psi to kPa, multiply 13.053 x 6.89476, resulting in 90 kPa.
