Convert Centimeter of water to Centipascal (cmH2O to Centipascal)

Centimeter of water (cmH2O) and Centipascal (Centipascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert centimeter of water to centipascal. This free online calculator tool makes it simple and easy to perform the conversion from cmH2O unit to the Centipascal 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 centimeter of water (symbol: cmH₂O) is a non-SI unit of pressure defined as the pressure exerted by a one-centimeter column of water under standard gravity. It is widely used in medical equipment, ventilation systems, HVAC engineering, and fluid mechanics because it provides a practical scale for measuring relatively low pressures. The unit is derived from the hydrostatic pressure of water and is described alongside other pressure units in the centimeter of water reference.

One centimeter of water is equal to 98.0665 pascals, 10 millimeters of water, 0.000980665 bar, 0.0142233 psi, and 0.000967841 standard atmosphere. The centimeter of water is commonly used whenever accurate measurement of low pressure is required.

The centipascal (symbol: cPa) is an SI-derived unit of pressure equal to one-hundredth (0.01) of a pascal. It is used to express relatively small pressure values in scientific calculations, laboratory measurements, and engineering applications where greater precision than the pascal is required. The centipascal uses the SI prefix centi, representing a factor of one-hundredth.

One centipascal is equal to 0.01 pascal, 10 millipascals, 10,000 micropascals, 0.0000001 bar, and 9.86923×10^-8 standard atmosphere. The centipascal provides a convenient way to represent small pressure values using SI units.
