The pound per square inch (psi) is the customary United States unit of pressure, one pound-force per square inch. It is used for tire pressure, air compressors and water and gas pressure in the United States, and for tires in the United Kingdom too.

The pascal (Pa) is the SI unit of pressure, one newton per square meter. It is a very small unit, so everyday pressures are usually given in kilopascals or hectopascals, but the pascal is the base of physics, acoustics and engineering formulas.
