About these units
Pascal (Pa). The pascal is the SI unit of pressure, one newton per square meter. Because it is small, practical values are often quoted in kilopascals, bar or atmospheres.
PSI (psi). Pounds per square inch (psi) is the US customary pressure unit, one pound-force applied to one square inch. Tire gauges, compressed air and hydraulics in the US are measured in psi.
