Millipascal
A millipascal (mPa) is a unit of pressure equal to one thousandth of a pascal, the SI unit of pressure.
History/Origin
The millipascal is derived from the pascal, which was named after Blaise Pascal. It is used in contexts requiring very small pressure measurements, but its usage is relatively uncommon due to the widespread adoption of the pascal.
Current Use
Millipascals are primarily used in scientific and engineering fields to measure very low pressures, such as in fluid dynamics, vacuum systems, and sensitive instrumentation within the 'Pressure' converter category of 'Common Converters'.
Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
