Micropascal
The micropascal (µPa) is a unit of pressure equal to one millionth of a pascal, used to measure very low pressures.
History/Origin
The micropascal was introduced as part of the SI unit system to quantify extremely small pressure values, especially in scientific and engineering contexts, though it is rarely used in practical applications.
Current Use
The micropascal is primarily used in scientific research, acoustics, and environmental monitoring where precise measurement of very low pressures is required.
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.
