Where this conversion is used
The pascal is the SI unit of pressure; the bar is a metric unit defined as exactly 100,000 Pa (100 kPa). Engineers use bar for everyday process and hydraulic pressures and pascal (or kPa and MPa) in calculations, standards and scientific work.
A common mistake is to treat 1 bar as atmospheric pressure. The standard atmosphere is 1.01325 bar = 101,325 Pa, so 1 bar is about 1.3 % lower.
Frequently asked questions
How many pascals are in 1 bar?
1 bar = 100,000 Pa. In the other direction, 1 Pa = 1×10⁻⁵ bar.
How do I convert bar to pascals?
Multiply the value in bar by 100,000. Example: 2.5 bar = 250,000 Pa.
Is 1 bar equal to 100 kPa or 101 kPa?
Exactly 100 kPa. 101.325 kPa is the standard atmosphere, which is 1.01325 bar. Several conversion sites mix the two up.
How many MPa is 1 bar?
1 bar = 0.1 MPa, so 10 bar = 1 MPa. Hydraulic and pressure-vessel ratings are often given in MPa.
