mbar to kPa Converter - Millibar to Kilopascal

Millibar (mbar) to Kilopascal (kPa)

Direct answer

1 mbar = 0.1 kPa

kPa = mbar × 0.1

Converter

Input

mbar

Result

0.1kPa

kPa = mbar × 0.1

mbar = kPa × 10

Example: 10 mbar = 10 × 0.1 = 1 kPa.

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

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

1 mbar = 0.1 kPa.

10 mbar = 1 kPa.

100 mbar = 10 kPa.

Use kPa = mbar × 0.1.

1 kPa = 10 mbar.

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