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.
Micropascal
The micropascal (µPa) is a unit of pressure equal to one millionth of a pascal, used to measure very low pressures.
History/Origin
The micropascal was introduced as part of the SI unit system to quantify extremely small pressure values, especially in scientific and engineering contexts, though it is rarely used in practical applications.
Current Use
The micropascal is primarily used in scientific research, acoustics, and environmental monitoring where precise measurement of very low pressures is required.
