atm to mmHg converter
1 atm = 760 mmHg
And 1 mmHg = 0.00131579 atm. Standard atmosphere to millimetres of mercury.
Formula
mmHg = atm × 760
A reading of 15 atm is 15 × 760 = 11,400 mmHg.

About these units
atm (standard atmosphere): Defined as 101,325 Pa, roughly sea-level air pressure.
mmHg (millimetres of mercury): Blood pressure and vacuum gauges, using the conventional 13.5951 g/cm³ mercury.
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.
