In the field of medicine and physiology, mm Hg stands for millimeters of mercury, a unit used to measure pressure. This unit is commonly used to measure blood pressure, atmospheric pressure, and pressure in various medical equipment.

What is mm Hg?

Millimeters of mercury (mm Hg) is a unit of pressure that is based on the pressure exerted by a column of mercury of one millimeter in height at the standard acceleration of gravity. It is often used as a unit of pressure in medical settings, particularly when measuring blood pressure.

Measuring Blood Pressure

When blood pressure is measured, it is typically expressed as two numbers, such as 120/80 mm Hg. The first number represents the systolic pressure, which is the pressure in the arteries when the heart muscle contracts. The second number represents the diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats.

Other Uses of mm Hg

Aside from measuring blood pressure, mm Hg is also commonly used to measure atmospheric pressure. Standard atmospheric pressure at sea level is approximately 760 mm Hg. In addition, mm Hg is used in devices such as barometers and manometers to measure pressure in various systems.

In conclusion, millimeters of mercury (mm Hg) is an important unit of pressure used in various applications, including the measurement of blood pressure and atmospheric pressure. Understanding this unit is crucial in the fields of medicine, meteorology, and engineering.


Mm Hg Examples

  1. The normal blood pressure is typically around 120/80 mm Hg.
  2. The barometric pressure is measured in millimeters of mercury (mm Hg).
  3. A mercury manometer is often used to measure pressure in units of mm Hg.
  4. High altitude can result in lower atmospheric pressure, measured in mm Hg.
  5. The pressure in a car tire is often recommended to be around 32 psi, equivalent to 218.79 mm Hg.
  6. A sphygmomanometer is a device used to measure blood pressure in units of mm Hg.
  7. Scuba divers use a dive computer to monitor their depth and pressure in mm Hg.
  8. At sea level, the atmospheric pressure is typically around 760 mm Hg.
  9. The pressure in a vacuum is often expressed in negative units of mm Hg.
  10. The boiling point of water decreases as altitude increases due to lower atmospheric pressure in mm Hg.
