About these units
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
mbar (millibar): Used for weather, vacuum and low differential pressures.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
