Illustration of a CO2 cartridge
459 psi (3,165 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: 459 psi × 0.00689476 = 3.1647 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 3.1647 MPa to psi, multiply 3.1647 x 145.038, resulting in 459 psi.

459 psi is also equal to:

  • 3164700 pascal
  • 3164.7 kPa
  • 31.647 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).
