5,004 psi (34,500 kPa) is comparable to the compressive strength of concrete.

Did you know? Concrete compressive strength is 30,000 kPa.

Typical structural concrete has a compressive strength of 20-40 MPa (20,000-40,000 kPa).

How to Convert Bar to MPa

1 bar = 0.1 MPa

MPa = Bar × 0.1

Example: 345 bar × 0.1 = 34.5 MPa

Reverse Conversion

To convert MPa back to bar:

  • Remember, 1 MPa equals 10 bar.
  • To convert 34.5 MPa to bar, multiply 34.5 x 10, resulting in 345 bar.

345 bar is also equal to:

  • 3.45 × 107 pascal
  • 34500 kPa
  • 5003.8 psi
About these units

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

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