mmHg to bar converter
1 mmHg = 0.00133322 bar
And 1 bar = 750.062 mmHg. Millimetres of mercury to bar.
Formula
bar = mmHg × 0.00133322
A reading of 15 mmHg is 15 × 0.00133322 = 0.0199984 bar.

About these units
mmHg (millimetres of mercury): Blood pressure and vacuum gauges, using the conventional 13.5951 g/cm³ mercury.
bar (bar): Close to one atmosphere; widely used for industrial and pneumatic gauges outside the US.
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.
