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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Millibar
A millibar (mbar) is a unit of pressure measurement equal to one-thousandth of a bar, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The millibar was introduced in the early 20th century as a convenient unit for meteorological measurements, replacing the bar in many applications due to its smaller size. It became widely adopted in weather reporting and atmospheric studies.
Current Use
Today, the millibar is still used in meteorology and atmospheric sciences to report atmospheric pressure, although it is gradually being replaced by the Pascal (Pa) in scientific contexts. It remains a standard unit in weather forecasts and reports.
