What is standard atmospheric pressure?

Standard atmospheric pressure is 101,325 pascals (Pa), 1 atmosphere (atm), 1.01325 bar, 14.696 PSI, or 760 mmHg at sea level.

How do I convert PSI to bar?

Divide the PSI value by 14.5038 to get bar. For example, 30 PSI ÷ 14.5038 = 2.069 bar.

What is mmHg used for?

mmHg (millimeters of mercury) is used primarily in medicine for blood pressure readings and in meteorology for atmospheric pressure.

What is the difference between gauge and absolute pressure?

Gauge pressure measures pressure relative to atmospheric pressure, while absolute pressure includes atmospheric pressure. Absolute = Gauge + Atmospheric.
