PSI to Pascal (psi to Pa)
Result
6,894.757293 Pascal
Formula
Pa = psi × 6,894.757293
1 psi = 6,894.757293 Pa, and 1 Pa = 0.000145037738 psi.
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 psi × 6,894.757293 = 6,894.7573 Pa
- 10 psi × 6,894.757293 = 68,947.573 Pa
- 100 psi × 6,894.757293 = 689,475.73 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.
