57,580 psi (397,000 kPa) is comparable to the cutting pressure of an industrial waterjet cutter.

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: 397 MPa × 10 = 3970 bar

Reverse Conversion

To convert bar back to MPa:

  • Remember, 1 bar equals 0.1 MPa.
  • To convert 3970 bar to MPa, multiply 3970 x 0.1, resulting in 397 MPa.

397 MPa is also equal to:

  • 3.97 × 108 pascal
  • 397000 kPa
  • 57580 psi
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.
