About these units
inHg (inches of mercury): Barometric pressure in US aviation and weather reports.
kPa (kilopascal): Common for HVAC, building ventilation and low-pressure gas work.
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.
