Decipascal
The decipascal (dPa) is a unit of pressure equal to one-tenth of a pascal, where 1 dPa = 0.1 Pa.
History/Origin
The decipascal was introduced as a metric unit to provide finer measurement options within the pressure unit system, though it is rarely used in practice due to the widespread adoption of the pascal.
Current Use
The decipascal is seldom used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific contexts or educational settings for illustrative purposes.
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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
