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.
Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
