Foot Water (4°c)
Foot water (4°C), symbol ftAq, is a unit of pressure representing the height of a water column at 4°C that exerts a specific pressure.
History/Origin
The foot water (4°C) has been used historically in engineering and scientific contexts to measure pressure, especially in water-related applications, as an alternative to other pressure units like inches of water or meters of water. Its usage dates back to traditional measurements in hydraulic and civil engineering.
Current Use
Today, foot water (4°C) is primarily used in specialized fields such as hydrology, water management, and engineering to measure low pressures, particularly in systems involving water flow and pressure head calculations.
Millibar
A millibar (mbar) is a unit of pressure measurement equal to one-thousandth of a bar, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The millibar was introduced in the early 20th century as a convenient unit for meteorological measurements, replacing the bar in many applications due to its smaller size. It became widely adopted in weather reporting and atmospheric studies.
Current Use
Today, the millibar is still used in meteorology and atmospheric sciences to report atmospheric pressure, although it is gradually being replaced by the Pascal (Pa) in scientific contexts. It remains a standard unit in weather forecasts and reports.
