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 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.
What is Millimeter of Mercury?
The millimeter of mercury (symbol: mmHg) is a non-SI unit of pressure based on the pressure exerted by a one-millimeter column of mercury under standard gravity. It is widely used in medicine, physiology, meteorology, and vacuum technology. Blood pressure is commonly measured in millimeters of mercury, making it one of the world's best-known pressure units. The unit is closely related to the Torr.
One millimeter of mercury is equal to 133.322 pascals, 0.133322 kilopascals, 0.00133322 bar, 0.0193368 pounds per square inch, and 0.00131579 standard atmosphere. The millimeter of mercury remains the standard unit for blood pressure measurements.
