Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
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.
