Did you know? Waterjet cutter is 414,000 kPa.

Industrial waterjets cut steel at 400-600 MPa (60,000-90,000 psi) using a hair-thin stream of water.

How to Convert MPa to Bar

1 MPa = 10 bar

Bar = MPa × 10

Example: 420 MPa × 10 = 4200 bar

Reverse Conversion

To convert bar back to MPa:

  • Remember, 1 bar equals 0.1 MPa.
  • To convert 4200 bar to MPa, multiply 4200 x 0.1, resulting in 420 MPa.

420 MPa is also equal to:

About these units

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

Bar: Metric pressure unit equal to exactly 100,000 pascals.
