How Do You Convert PSI to Bar and Pascals?

To convert PSI (pounds per square inch) to Bar, multiply PSI by 0.0689476 (1 Bar = 14.5038 PSI). To convert PSI to Pascals (Pa), multiply PSI by 6,894.76 (1 PSI = 6,894.757 Pa). Standard atmospheric pressure (1 atm) equals 1.01325 Bar, 14.6959 PSI, or 101,325 Pa.

Frequently Asked Questions

Divide PSI by 14.5038 (or multiply by 0.0689476): `Bar = PSI × 0.0689476`. For example, 32 PSI equals 2.206 Bar.
Standard atmospheric pressure at sea level (1 atm) equals 101,325 Pascals (101.325 kPa), 1.01325 Bar, 14.6959 PSI, or 760 mmHg (Torr).
There are exactly 100,000 Pascals (100 kPa or 0.1 MPa) in 1 Bar of pressure.
mmHg is primarily used in medicine for blood pressure measurement (e.g., 120/80 mmHg) and in barometric weather reporting.
Gauge pressure (psig) measures pressure relative to ambient atmospheric pressure, whereas absolute pressure (psia) measures pressure relative to a perfect vacuum (Absolute = Gauge + Atmospheric).
1 standard atmosphere (1 atm) equals exactly 101,325 Pascals (101.325 kPa or 14.6959 psi).
