What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Centimeter of Mercury?
The centimeter of mercury (symbol: cmHg) is a non-SI unit of pressure based on the pressure exerted by a one-centimeter column of mercury under standard gravity. It has traditionally been used in scientific instruments, laboratory measurements, and vacuum systems. Although the pascal is the SI unit of pressure, the centimeter of mercury is still encountered in specialized applications. It is closely related to the Torr and other mercury-based pressure units.
One centimeter of mercury is equal to 1,333.22 pascals, 10 millimeters of mercury, 0.0133322 bar, 0.193367 psi, and 0.0131579 standard atmosphere. This unit remains useful for comparing pressure values in traditional measurement systems.
What is Feet of water?
The foot of water (symbol: ftH₂O or ftH2O) is a non-SI unit of pressure based on the pressure exerted by a one-foot column of water under standard gravity. It is commonly used in plumbing, HVAC systems, fluid mechanics, and water distribution networks to measure relatively low pressures. Although the pascal is the SI unit of pressure, the foot of water remains widely used in engineering applications involving liquids. More information can be found in the water column reference.
One foot of water is equal to 2,989.07 pascals, 12 inches of water, 0.0298907 bar, 0.433527 psi, and 0.029503 standard atmosphere. The foot of water is widely used for measuring hydrostatic and fluid system pressures.
