These measurements are in general given relative to the current atmospheric pressure: for example, a blood pressure of 120 mmHg, when the current atmospheric pressure is 760 mmHg, means 880 mmHg relative to perfect vacuum.
The abbreviation mmHg stands for millimeters of mercury, representing a specialized unit of pressure widely adopted in medicine. This unit serves as the international standard for quantifying pressure, most notably when measuring a person’s blood pressure.
Blood pressure is the amount of force your blood uses to get through your arteries. A normal blood pressure reading for most adults is below 120/80 mmHg.
Millimeters of mercury is a non-SI unit of Pressure. The symbol for millimeters of mercury is mmHg. It is equal to a pressure of 133.3224 pascals or 0.00131579 atmospheres. 1 mmHg is also equal to 1 Torr.
It stands for millimeter of mercury, a unit of pressure. Imagine a tall glass tube filled with mercury (yes, that shiny, silvery liquid metal!) – the pressure exerted by a one-millimeter column of mercury is what we measure as 1 mmHg. Sounds cool, right?
One mmHg is the pressure exerted at the bottom of a vertical column exactly 1 millimeter deep of a fluid whose density is exactly 13.5951 grams per cubic centimeter, at a location where the acceleration due to gravity is exactly 980.665 centimeters per second per second.
