Illustration of a CO2 cartridge
477 psi (3,289 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 MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 477 psi × 0.00689476 = 3.2888 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 3.2888 MPa to psi, multiply 3.2888 x 145.038, resulting in 477 psi.

477 psi is also equal to:

  • 3288800 pascal
  • 3288.8 kPa
  • 32.888 bar
About these units

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

MPa: SI-derived pressure unit equal to 1,000,000 pascals (10⁶ Pa).
