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 KPa

1 MPa = 1000 kPa

KPa = MPa × 1000

Example: 3 MPa × 1000 = 3000 kPa

Reverse Conversion

To convert kPa back to MPa:

  • Remember, 1 kPa equals 0.001 MPa.
  • To convert 3000 kPa to MPa, multiply 3000 x 0.001, resulting in 3 MPa.

3 MPa is also equal to:

About these units

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