Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are required.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
