kPa to mbar Converter - Kilopascal to Millibar

Kilopascal (kPa) to Millibar (mbar)

Direct answer

1 kPa = 10 mbar

mbar = kPa × 10

Converter

Input

kPa

Result

10mbar

mbar = kPa × 10

kPa = mbar × 0.1

Example: 10 kPa = 10 × 10 = 100 mbar.

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

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

1 kPa = 10 mbar.

10 kPa = 100 mbar.

100 kPa = 1,000 mbar.

Use mbar = kPa × 10.

1 mbar = 0.1 kPa.

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