Convert Feet of water to Decapascal (ftH2O to Decapascal)

Feet of water (ftH2O) and Decapascal (Decapascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert feet of water to decapascal. This free online calculator tool makes it simple and easy to perform the conversion from ftH2O unit to the Decapascal unit.

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.

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.

Decapascal (symbol: daPa) is a metric unit of pressure equal to 10 pascals. The decapascal is commonly used in acoustics, audiology, meteorology, and engineering, where pressure values are conveniently expressed in multiples of ten pascals. One decapascal is exactly equal to 0.1 hectopascal, 0.01 kilopascal, or 0.0001 bar. It is frequently converted to pascals, hectopascals, and kilopascals for scientific measurements, atmospheric pressure analysis, and engineering calculations.
