How to Convert Megapascal to Bar
- 1 MPa = 10 bar
- 1 bar = 0.1 MPa
- Example: convert 15 MPa to bar: 15 MPa = 15 × 10 bar = 150 bar
Formula
bar = MPa × 10
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 bar = 10⁵ Pa (exact, by definition)
- 1 MPa = 1000000 Pa ÷ 100000 Pa per bar = 10 bar
Both units are defined exactly, so the factor is exact. Megapascal definition: megapascal; Bar definition: bar.
Worked examples
- A 20 MPa hydraulic pressure is 200 bar.
20 MPa × 10 = 200 bar - A 0.6 MPa compressed-air system is at 6 bar.
0.6 MPa × 10 = 6 bar
