About bar and PSI

Bar (bar). The bar is a metric pressure unit equal to 100,000 pascals, very close to atmospheric pressure at sea level (1 atm = 1.01325 bar).

PSI (psi). Pounds per square inch (psi) is a US customary pressure unit, used for tyre pressure, air compressors and plumbing. One psi is about 6,894.76 pascals.
