This calculator enables seamless conversion of pressure values from Millimeter of Water Column (mmWC) to Pascal (Pa), widely used in engineering, environmental sciences, and industrial calibration applications requiring precise pressure measurements.
Use this mmH2O to Pa calculator to quickly convert millimeter of water column pressure into Pascal (Pa). This conversion is commonly used in HVAC, process instrumentation, calibration, and low-pressure measurement applications. The standard conversion factor is 1 mmH2O = 9.80665 Pa.
What is mmH2O?
mmH2O stands for millimeters of water column. It is a pressure unit based on the pressure exerted by a 1 mm high water column under standard conditions. This unit is commonly used for low-pressure measurement in HVAC systems, laboratory work, and instrumentation.
What is Pascal (Pa)?
Pascal (Pa) is the SI unit of pressure. One Pascal is equal to one Newton per square meter (N/m²). It is the standard unit used in scientific, industrial, and engineering pressure calculations.
mmH2O to Pa Formula
Pressure in Pa = Pressure in mmH2O × 9.80665
How to Convert mmWC to Pa: Example Calculation
Suppose you have a pressure of 50 mmWC. To convert it to Pa:
50?mmWC×9.80665=490.3325?Pa
Thus, 50 mmWC is equal to approximately 490.33 Pa.
