Centipascal
The centipascal (cPa) is a unit of pressure equal to one hundredth of a pascal, where 1 pascal (Pa) is the SI unit of pressure defined as one newton per square meter.
History/Origin
The centipascal was introduced as a smaller unit of pressure for more precise measurements, particularly in scientific and engineering contexts, although it is not widely used in practice. It derives from the pascal, the SI base unit established in 1960.
Current Use
The centipascal is rarely used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific literature or calibration contexts where fine pressure distinctions are necessary.
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.
