Bar to Pascal (bar to Pa)
Result
100,000 Pascal
Formula
Pa = bar × 100,000
1 bar = 100,000 Pa, and 1 Pa = 0.00001 bar.
The pascal is one newton per square metre. The bar is exactly 100,000 Pa, the standard atmosphere exactly 101,325 Pa, the torr exactly 1/760 atm, and psi is one pound-force per square inch (6,894.757 Pa).
Worked examples
- 1 bar × 100,000 = 100,000 Pa
- 10 bar × 100,000 = 1,000,000 Pa
- 100 bar × 100,000 = 10,000,000 Pa
Common mistakes
- Tyre and compressor gauges read gauge pressure — pressure above the surrounding air. Absolute pressure is about 1 atm (14.7 psi, 1.013 bar) higher.
- Weather maps use hectopascals (1 hPa = 100 Pa = 1 millibar); standard sea-level pressure is 1,013.25 hPa.
- Torr and mmHg differ by less than one part per million and are interchangeable for practical purposes.
