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.
Inch Water (4°c)
Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.
History/Origin
The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.
Current Use
Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.
