How do you convert pascals to millibars?

To convert pascals to millibars, divide the number of pascals by 100. 1 Pa = 0.01 mbar.

Conversion formula

Millibar = Pascal ÷ 100

Pascals, millibars and hectopascals

1 mbar = 100 Pa, so divide pascals by 100 to get millibars: 101,325 Pa = 1,013.25 mbar, the standard atmosphere.

A millibar is exactly one hectopascal (hPa). Weather maps use hPa, while vacuum gauges and older instruments often show mbar — the numbers are identical.
