Relation Between Bar And Pascal

The pressure is expressed in many units across the globe. Bar and Pascal are the units representing pressure. A pascal is one newton of force acting on the 1m2 area. A bar is used to express atmospheric pressure. The relation between bar and pascal is useful in solving the problem.

What is the Relation Between Bar and Pascal?

The units for pressure (Pressure is the force against a surface: Formulated as Force per area). Bar and pascal relation can be mathematically expressed as:

Bar to pascal formula 1 bar = 105 pascal
Pascal to bar formula 1 pascal = 10-5 bar or 0.01mbar

In order to understand the relation. It is important to know the terms individually.

Definition Symbol Formula Fundamental unit
1 Pascal The pressure exerted due to 1N of force acting on 1 m2 area. Pa 1Pa=1N/m2 Pa=kg/m.s2
1 Bar Unit of pressure almost similar to atmosphere unit bar 1bar=10,000N/m2 bar=kg/m.s2

Conversion of Bar and Pascal

Below table contains some of the commonly used values of pressure:

Units Values
1 bar to kilopascal 1bar = 100 kilopascal
1 bar to mPa 1 bar = 0.1 mPa (megapascal)
mbar to pascal 1mbar = 100Pa
1 bar to atm 1 bar = 0.986923
