Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
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.
