MPa to mbar Converter - Megapascal to Millibar

Megapascal (MPa) to Millibar (mbar)

Direct answer

1 MPa = 10,000 mbar

mbar = MPa × 10,000

Converter

Input

MPa

Result

10,000mbar

mbar = MPa × 10,000

MPa = mbar × 0.0001

Example: 10 MPa = 10 × 10,000 = 100,000 mbar.

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

1
Rewrite MPa in the base unit
$1 MPa = 1, 000, 000 Pa$
2
Rewrite mbar in the base unit
$1 mbar = 100 Pa$
3
Forward conversion
$1 MPa = \frac{1 , 000 , 000 Pa}{100 Pa} \times 1 mbar = \frac{1 , 000 , 000}{100} mbar = 10, 000 mbar$
4
Reverse conversion
$1 mbar = \frac{100 Pa}{1 , 000 , 000 Pa} \times 1 MPa = \frac{100}{1 , 000 , 000} MPa = 0.0001 MPa$

1 MPa = 10,000 mbar.

10 MPa = 100,000 mbar.

100 MPa = 1,000,000 mbar.

Use mbar = MPa × 10,000.

1 mbar = 0.0001 MPa.

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