About Millimeters of Mercury (mmHg)

Millimeters of mercury is the standard unit for blood pressure readings worldwide (e.g., 120/80 mmHg for a healthy adult) and for barometric pressure in some contexts. The unit derives from the height of a mercury column in a manometer, and 760 mmHg equals one standard atmosphere.

About Atmosphere (atm)

Standard atmosphere (atm) equals exactly 101,325 pascals and represents the average air pressure at sea level. Scuba divers experience one additional atmosphere for every 10 meters of seawater depth, and pressurized aircraft cabins maintain roughly 0.75 atm at cruising altitude.
