How to Convert Millibars to Bars
The millibar and bar are both units of pressure. By definition, 1 bar equals exactly 1000 millibars. This means to convert millibars to bars, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 mbar to bars:
We need to convert millibars to bars
Since 1 bar = 1000 mbar, divide by 1000
5 ÷ 1000 = 0.005
5 mbar = 0.005 bar

About These Units
Millibar (mbar)
A millibar (mbar) equals 100 Pascals or one hectopascal. Millibars are used in meteorology for atmospheric pressure and weather forecasting. Standard sea level pressure is 1013.25 mbar. Hurricanes have central pressures below 950 mbar.
Bar (bar)
A bar equals 100,000 Pascals or approximately 14.5 PSI. Bar is slightly less than standard atmospheric pressure (1.01325 bar). Bars measure tire pressure, compressed gas cylinders, scuba tank pressure (200-300 bar), and industrial processes.
