mmHg to psi converter
1 mmHg = 0.0193368 psi
And 1 psi = 51.7149 mmHg. Millimetres of mercury to pounds per square inch.
Formula
psi = mmHg × 0.0193368
A reading of 15 mmHg is 15 × 0.0193368 = 0.290052 psi.

About these units
mmHg (millimetres of mercury): Blood pressure and vacuum gauges, using the conventional 13.5951 g/cm³ mercury.
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.
