Illustration of a CO2 cartridge
403 psi (2,779 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: 403 psi × 6894.76 = 2778600 Pa

Reverse Conversion

To convert pascals back to psi:

  • Remember, 1 pascal equals 0.000145038 psi.
  • To convert 2778600 Pa to psi, multiply 2778600 x 0.000145038, resulting in 403 psi.

403 psi is also equal to:

  • 2778.6 kPa
  • 27.786 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).
