A metric unit of pressure equal to 100,000 Pascals. It's commonly used in Europe and many international industries for measuring tire pressure, hydraulic systems, and industrial applications.
1 bar is approximately equal to atmospheric pressure at sea level (14.5038 psi).
An imperial unit of pressure equal to the pressure exerted by one pound-force applied to an area of one square inch. It's commonly used in the United States for tire pressure, plumbing, and various industrial applications.
Psi is part of the imperial system of units, while bar is part of the metric system.
