Dekapascal
The dekapascal (daPa) is a unit of pressure equal to ten pascals, where one pascal (Pa) is the SI derived unit of pressure representing one newton per square meter.
History/Origin
The dekapascal was introduced as a metric prefix-based unit to simplify the expression of larger pressures, particularly in fields like meteorology and engineering, aligning with the SI system's prefixes. Its usage is relatively uncommon compared to the pascal.
Current Use
The dekapascal is occasionally used in scientific and technical contexts to express pressure measurements more conveniently, especially in applications where pressures are in the range of thousands of pascals. It is part of pressure conversions within the 'Common Converters' category.
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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
