bar to MPa Converter - Bar to Megapascal

Bar (bar) to Megapascal (MPa)

Direct answer

1 bar = 0.1 MPa

MPa = bar × 0.1

Converter

Input

bar

Result

0.1MPa

MPa = bar × 0.1

bar = MPa × 10

Example: 10 bar = 10 × 0.1 = 1 MPa.

Express both bar and MPa in the same base unit Pa (pascal), then cancel the shared base unit.

1
Rewrite bar in the base unit
$1 bar = 100, 000 Pa$
2
Rewrite MPa in the base unit
$1 MPa = 1, 000, 000 Pa$
3
Forward conversion
$1 bar = \frac{100 , 000 Pa}{1 , 000 , 000 Pa} \times 1 MPa = \frac{100 , 000}{1 , 000 , 000} MPa = 0.1 MPa$
4
Reverse conversion
$1 MPa = \frac{1 , 000 , 000 Pa}{100 , 000 Pa} \times 1 bar = \frac{1 , 000 , 000}{100 , 000} bar = 10 bar$

AI text is for interpretation only. The page calculator remains the source of truth for numeric results.

1 bar = 0.1 MPa.

10 bar = 1 MPa.

100 bar = 10 MPa.

Use MPa = bar × 0.1.

1 MPa = 10 bar.

Use the conversion factor and round the result to the precision required by your calculation.
