inHg to psi converter
1 inHg = 0.491154 psi
And 1 psi = 2.03602 inHg. Inches of mercury to pounds per square inch.
Formula
psi = inHg × 0.491154
A reading of 15 inHg is 15 × 0.491154 = 7.36731 psi.

About these units
inHg (inches of mercury): Barometric pressure in US aviation and weather reports.
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
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.
