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.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
