Illustration of a CO2 cartridge
421 psi (2,903 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: 421 psi × 6894.76 = 2902700 Pa

Reverse Conversion

To convert pascals back to psi:

  • Remember, 1 pascal equals 0.000145038 psi.
  • To convert 2902700 Pa to psi, multiply 2902700 x 0.000145038, resulting in 421 psi.

421 psi is also equal to:

  • 2902.7 kPa
  • 29.027 bar
About these units

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

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).
