What is PSI?

PSI (short for pound-force per square inch) is a unit of pressure or of stress based on avoirdupois units.

It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

Common Uses

PSI is the standard unit of pressure in the United States and the United Kingdom for measuring things like tire pressure, air compressor output, and hydraulic systems.

The bar is a metric unit of pressure, but not part of the International System of Units (SI).

It is defined as exactly 100,000 pascals, which is slightly less than the current average atmospheric pressure on Earth at sea level.

Common Uses

The bar is commonly used in meteorology, engineering, and for measuring the pressure of compressed gases and liquids.
