Illustration of a CO2 cartridge
493 psi (3,400 kPa) is comparable to the pressure inside a CO₂ cartridge or small gas cylinder.

Did you know? CO2 cartridge is 3,000 kPa.

Small CO2 cartridges (for soda makers, paintball) operate at about 3,000 kPa (435 psi) at room temperature.

How to Convert KPa to Psi

1 kPa = 0.145038 psi

Psi = KPa × 0.145038

Example: 3400 kPa × 0.145038 = 493.13 psi

Reverse Conversion

To convert psi back to kPa:

  • Remember, 1 psi equals 6.89476 kPa.
  • To convert 493.13 psi to kPa, multiply 493.13 x 6.89476, resulting in 3400 kPa.

3400 kPa is also equal to:
