Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure by quantifying pounds force exerted on a one-inch square area, used in the US customary system for tire, hydraulic, and atmospheric pressure, reflecting force distribution over a specific area.
bar
Bar is a metric unit of pressure equal to 100,000 pascals, used in meteorology, engineering, and industry to describe force per unit area, especially in contexts like tire inflation, scuba, and industrial processes, providing a standard measure across systems.
Conversion FAQs
Why is psi converted to bar in pressure measurement?
