Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure by indicating how many pounds of force are exerted over one square inch. It is primarily used in the US to quantify tire pressures, hydraulic systems, and other pressure-related measurements.
bar
Bar is a metric unit of pressure equal to 100,000 Pascals, roughly equivalent to Earth’s atmospheric pressure at sea level. It is common in science and engineering for measuring pressure in various systems like tanks, pipes, and scientific experiments.
