About Millimeters of Mercury and PSI
One millimeter of mercury (mmHg) equals approximately 0.01934 PSI. Blood pressure is universally measured in mmHg — a reading of 120/80 mmHg equals about 2.32/1.55 PSI. Barometric pressure is also expressed in mmHg (760 mmHg at standard atmosphere). While PSI is not used for blood pressure clinically, this conversion is needed for engineering applications where medical device pressure specifications must align with industrial pressure standards.
