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 Millibar?
The millibar (symbol: mbar) is a non-SI unit of pressure equal to one-thousandth of a bar or exactly 100 pascals. It has been widely used in meteorology to report atmospheric pressure and remains common in weather forecasts, although the SI unit hectopascal has largely replaced it. One millibar is numerically equal to one hectopascal. More information is available in the bar (unit) reference.
One millibar is equal to 100 pascals, 1 hectopascal, 0.1 kilopascal, 0.001 bar, and 0.000986923 standard atmosphere. The millibar remains a familiar unit for atmospheric pressure worldwide.
