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.
Atmosphere Technical
The atmosphere technical (at) is a unit of pressure defined as exactly 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The atmosphere technical was established as a standard unit of pressure in the early 20th century to facilitate scientific and engineering calculations involving atmospheric pressure, aligning with the international standard atmosphere (ISA).
Current Use
It is primarily used in scientific, meteorological, and engineering contexts to quantify atmospheric pressure, especially in fields requiring standardized pressure measurements at sea level.
