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.
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.
