Conversion Definitions

psi

Psi, pounds per square inch, is a unit of pressure measuring force applied over an area, mainly used in the US. It indicates how many pounds of force are exerted on one square inch of surface, common in tire, plumbing, and industrial pressure measurements.

bar

Bar is a metric pressure unit equal to 100,000 Pascals. It is widely used in Europe and in scientific contexts to measure force per unit area, often in meteorology, engineering, and high-pressure systems, providing an alternative to psi for pressure readings.
