Illustration of steel beam yield strength
37,420 psi (258,000 kPa) is comparable to the yield strength of structural steel.

Did you know? Steel yield strength is 250,000 kPa.

Mild structural steel (A36) yields at about 250 MPa (250,000 kPa / 36,000 psi).

How to Convert MPa to Bar

1 MPa = 10 bar

Bar = MPa × 10

Example: 258 MPa × 10 = 2580 bar

Reverse Conversion

To convert bar back to MPa:

  • Remember, 1 bar equals 0.1 MPa.
  • To convert 2580 bar to MPa, multiply 2580 x 0.1, resulting in 258 MPa.

258 MPa is also equal to:

  • 2.58 × 108 pascal
  • 258000 kPa
  • 37420 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.
