Pascals to Bar Conversion Table
Common values, ready to copy:
| pascals | bar |
|---|---|
| 1 Pa | 1.0000e-5 bar |
| 2 Pa | 2.0000e-5 bar |
| 5 Pa | 5.0000e-5 bar |
| 10 Pa | 0.0001 bar |
| 25 Pa | 0.00025 bar |
| 50 Pa | 0.0005 bar |
| 100 Pa | 0.001 bar |
| 1,000 Pa | 0.01 bar |
Formula
bar = pascals × 0.00001
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
About Pascals and Bar
Pascals (Pa): The SI unit of pressure, defined as one newton per square meter; named for Blaise Pascal, who established fundamental principles of fluid pressure in the 17th century. Common uses: Scientific work, weather (atmospheric pressure in hectopascals or kilopascals), and engineering specifications.
Bar (bar): Defined as exactly 100,000 pascals, or roughly atmospheric pressure at sea level; the name comes from the Greek baros meaning weight. Common uses: European weather reports, tire pressure in some countries (and motorcycles globally), gas cylinder pressures, and brewery/winery pressures.
How the conversion works
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
The exact relationship is bar = pascals × 0.00001, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between pascals and bar comes up wherever pressure measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
