Illustration of a CO2 cartridge
400 psi (2,758 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 Pascal

1 psi = 6894.76 pascals

Pascal = Psi × 6894.76

Example: 400 psi × 6894.76 = 2757900 Pa

Reverse Conversion

To convert pascals back to psi:

  • Remember, 1 pascal equals 0.000145038 psi.
  • To convert 2757900 Pa to psi, multiply 2757900 x 0.000145038, resulting in 400 psi.
