Inch of Water (inH₂O) to Pascal (Pa) Pressure Unit Conversion Calculator

This calculator enables you to quickly convert pressure values from Inches of Water (inH₂O) to Pascals (Pa), commonly used in HVAC, fluid dynamics, and various engineering applications requiring accurate low-pressure measurements.

Definition: Inch of Water (inH₂O)

The Inch of Water (inH₂O) is a non-SI unit of pressure that represents the pressure exerted by a 1-inch column of water at 4°C (39.2°F) under standard gravity. It is commonly used in HVAC systems and other applications involving airflow and low-pressure measurement.

Definition: Pascal (Pa)

The Pascal (Pa) is the SI unit of pressure, defined as one newton per square meter (N/m²). It is a widely recognized unit in scientific, engineering, and industrial fields.

Formula for inH₂O to Pa Conversion:

Pressure in Pa=Pressure in inH₂O×249.0889

How to Convert inH₂O to Pa: Example Calculation

Suppose you have a pressure of 10 inH₂O. To convert it to Pascals (Pa):

10 inH₂O×249.0889=2490.889 Pa

Therefore, 10 inH₂O is equal to approximately 2490.89 Pa.
