What is Pound per square inch?

The pound per square inch is a unit of pressure expressing force in pounds-force applied to an area of one square inch. It is widely used in the United States and United Kingdom. Car tire pressure in the US is typically 30 to 35 psi, and industrial compressed air systems commonly operate at 90 to 150 psi. Fire sprinkler systems, natural gas pipelines, and hydraulic tools all use psi ratings. One psi equals approximately 6,895 pascals.

What is Pascal?

The pascal is the SI unit of pressure, defined as one newton of force per square meter. Named after French mathematician and physicist Blaise Pascal, it is the foundation for related units like the hectopascal used in weather reports. Since one pascal is a very small amount of pressure, practical applications typically use kilopascals (kPa) or megapascals (MPa). In materials engineering, stress and tensile strength are expressed in megapascals or gigapascals.
