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 Pound Force Per Square Inch?
The pound force per square inch (symbol: psi or lbf/in2) is a non-SI unit of pressure equal to one pound-force applied over an area of one square inch. It is one of the most widely used pressure units in the United States for measuring tire pressure, hydraulic systems, compressed gases, and industrial equipment. Although the pascal is the SI unit of pressure, the psi remains the preferred unit in many engineering applications. More information is available in the pounds per square inch article.
One pound force per square inch is equal to 6,894.76 pascals, 6.89476 kilopascals, 0.0689476 bar, 0.068046 standard atmosphere, and 0.0703069 kilogram-force per square centimetre. The psi is one of the world's most recognized units for measuring pressure.
