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.
Inch Mercury (32°f)
Inch of mercury at 32°F (inHg) is a unit of pressure measurement representing the height of a mercury column in inches, used primarily in meteorology and aviation.
History/Origin
The inch of mercury originated from barometric pressure measurements using a mercury barometer, with its use dating back to the 18th century. It became a standard unit in weather reporting and altitude measurement.
Current Use
Today, inHg is primarily used in meteorology to report atmospheric pressure, especially in the United States, and in aviation for altitude and pressure readings.
