Formula

Formula
MPa = bar × 0.1

Multiply any value in bar by 0.1 to obtain the value in megapascals.

Worked example

Convert 50 bar to MPa.

  1. 01Start with 50 bar.
  2. 02Multiply by the conversion factor: 50 × 0.1 = 5 MPa.
Result50 bar = 5 MPa

FAQ

What is the conversion factor from bar to MPa?
1 bar equals 0.1 MPa. To convert, multiply the value in bar by 0.1.
How do I convert 1 bar to MPa?
1 bar = 0.1 MPa. For any value, multiply by 0.1.
How do I convert MPa back to bar?
Divide by the same factor — or equivalently, multiply by 10. So 1 MPa = 10 bar.
When would I need to convert bar to megapascal?
Pressure conversions between bar and MPa are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
Yes. Both bar and MPa are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
