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 Pounds per Square Inch (psi)
Pounds per square inch is the most common pressure unit in the United States, used for tire pressure (typically 30-35 psi for passenger cars), air compressor ratings, and water pressure in plumbing. Fire hydrants deliver water at 40-80 psi, and scuba tank pressures reach 3,000 psi.
