- Illustration of Division:
- Micropascal = inh2o ÷ 0.000000004
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 Inch of water?
The inch of water (symbol: inH₂O or inH2O) is a non-SI unit of pressure based on the pressure exerted by a one-inch column of water under standard gravity. It is commonly used in HVAC systems, ventilation, gas distribution, and fluid mechanics to measure low-pressure differences. Although the pascal is the SI unit of pressure, the inch of water remains widely used because it provides a convenient scale for low-pressure applications. More information is available in the inch of water reference.
One inch of water is equal to 249.089 pascals, 2.54 centimeters of water, 0.00249089 bar, 0.0361263 psi, and 0.249089 kilopascals. The inch of water is one of the most commonly used units for measuring low gas and air pressures.
What is Micropascal?
The micropascal (symbol: µPa) is an SI-derived unit of pressure equal to one millionth (10-6) of a pascal. It is commonly used in acoustics, sound pressure measurements, atmospheric science, and precision laboratory applications involving extremely small pressure variations. The micropascal uses the SI prefix micro, representing a factor of one millionth.
One micropascal is equal to 0.000001 pascal, 0.001 millipascal, 1,000 nanopascals, 1×10-11 bar, and 9.86923×10-12 standard atmosphere. The micropascal is particularly important in acoustics, where it is used as the reference unit for sound pressure levels.
