Psi to Millimeter of Water Column (mmWC) Pressure Unit Conversion Calculator

This calculator allows you to convert pressure values from pounds per square inch (psi) to millimeters of water column (mmWC), which is essential for various industrial, HVAC, and process control applications.

Definition: Pound-force per Square Inch (psi)

Pounds per square inch (symbol: psi) is a unit of pressure used in the imperial and US customary systems. It represents the pressure resulting from one pound-force applied to an area of one square inch and is commonly used in hydraulics, pneumatics, and various industrial applications.

Definition: Millimeter of Water Column (mmWC)

A millimeter of water column (symbol: mmWC or mmH₂O) is a unit of pressure that represents the pressure exerted by a 1 mm high column of water at 4°C under standard gravity. It is frequently used in low-pressure systems, including HVAC and water treatment applications.

Formula for Psi to mmWC Conversion:

Pressure in mmWC=Pressure in Psi×703.07

How to Convert Psi to mmWC: Example Calculation

Suppose you have a pressure of 1 psi.

To convert it to mmWC:

1 psi×703.07=703.07 mmWC

So, 1 psi is equal to 703.07 mmWC.
