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.
Picopascal
The picopascal (pPa) is a unit of pressure equal to 10^-12 pascals, representing an extremely small pressure measurement.
History/Origin
The picopascal was introduced as part of the SI prefixes to measure very low pressures, primarily in scientific research and specialized fields requiring high precision. Its usage has been limited due to the small magnitude of the unit.
Current Use
Currently, the picopascal is rarely used in practical applications but may be employed in scientific experiments involving ultra-low pressure measurements or in theoretical contexts where extremely small pressure values are relevant.
