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 bar equals exactly 100,000 pascals, which is very close to atmospheric pressure at sea level. It is used for tire and gas pressure in Europe, for scuba tanks (water adds about one bar per 10 meters of depth), and in hydraulics and boilers.
