Illustration of a CO2 cartridge
405 psi (2,792 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 Psi to KPa

1 psi = 6.89476 kPa

KPa = Psi × 6.89476

Example: 405 psi × 6.89476 = 2792.4 kPa

Reverse Conversion

To convert kPa back to psi:

  • Remember, 1 kPa equals 0.145038 psi.
  • To convert 2792.4 kPa to psi, multiply 2792.4 x 0.145038, resulting in 405 psi.

405 psi is also equal to:

  • 2792400 pascal
  • 27.924 bar
About these units

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.

KPa: SI-derived pressure unit equal to 1,000 pascals (10³ Pa).
