Conversion Definitions
Bar
A bar is a metric unit measuring pressure, roughly equal to atmospheric pressure at sea level, with 1 bar equaling 100,000 pascals. It’s used in engineering, meteorology, and other fields to express pressure levels.
Psi
Pounds per square inch (psi) is a unit of pressure common in the United States, representing force in pounds applied over one square inch of area. It is widely used for tire pressures, hydraulics, and other pressure measurements.
