Illustration of a CO2 cartridge
456 psi (3,144 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: 456 psi × 0.00689476 = 3.144 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 3.144 MPa to psi, multiply 3.144 x 145.038, resulting in 456 psi.

456 psi is also equal to:

  • 3144000 pascal
  • 3144 kPa
  • 31.44 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).

Frequently Asked Questions
