How to convert Mm of Mercury to Atmosphere
Multiply the mm of mercury value by 0.00131579: 1 mmHg = 0.00131579 atm. Going the other way, 1 atm = 760.002 mmHg, so divide by 0.00131579 or use the Atmosphere to Mm of Mercury converter.
About these units
Mm of Mercury (mmHg)
A millimeter of mercury is the pressure exerted by a column of mercury 1 mm high, about 133.3 pascals. Blood pressure is measured in mmHg.
Atmosphere (atm)
A standard atmosphere is defined as exactly 101,325 pascals, roughly the average air pressure at sea level. It is about 14.7 psi or 1.013 bar.
