Unit Definitions
What is a Millimeter of Mercury (mmHg)?
The millimeter of mercury (mmHg) is a unit of pressure defined by the height of a column of mercury in a barometer.
History
Historically, mmHg was used as a standard for measuring blood pressure and atmospheric pressure, originating from the barometric pressure measurements in the 17th century.
Current Use
Today, mmHg is commonly used in medicine, particularly in measuring blood pressure, as well as in meteorology for atmospheric pressure readings.
What is a PSI (psi)?
Pounds per square inch (psi) is a unit of pressure defined as the pressure resulting from a force of one pound-force applied to an area of one square inch.
History
The psi unit has its origins in the United States and is widely used in various industries, especially in engineering and automotive applications since the early 20th century.
Current Use
Currently, psi is frequently used to measure tire pressure, hydraulic systems, and in various industrial applications, making it a practical unit in everyday use.
