Illustration of a CO2 cartridge
390 psi (2,686 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 MPa to Psi

1 MPa = 145.038 psi

Psi = MPa × 145.038

Example: 2.686 MPa × 145.038 = 389.57 psi

Reverse Conversion

To convert psi back to MPa:

  • Remember, 1 psi equals 0.00689476 MPa.
  • To convert 389.57 psi to MPa, multiply 389.57 x 0.00689476, resulting in 2.686 MPa.

2.686 MPa is also equal to:

  • 2686000 pascal
  • 2686 kPa
  • 26.86 bar
