Definitions of Measurement Units

Bar (bar): A unit of pressure in the metric system, equal to 100,000 Pascals (Pa). Commonly used in meteorology, engineering, and industrial applications. It is close to standard atmospheric pressure at sea level (~1.013 bar).

Pounds per Square Inch (PSI): A unit of pressure in the imperial system, mainly used in the United States and the UK. It represents the force of one pound applied to an area of one square inch. Used in tire pressure, hydraulics, and various industrial settings.

Conversion Formula

To convert bar to PSI, multiply the pressure in bar by 14.5038:

P(PSI) = P(bar) × 14.5038

To convert PSI to bar, multiply the pressure in PSI by 0.0689476:

P(bar) = P(PSI) × 0.0689476
