PSI to Inches of Water Conversion Calculator
Convert pressure from PSI to inches of water using our free online calculator.
What is the PSI to Inches of Water Conversion Calculator & How does it work?
Pressure is a fundamental physical quantity that measures the force applied per unit area. One common unit of pressure is pounds per square inch (PSI), while another is inches of water, which represents the height of a column of water exerting one pound per square inch of pressure at 39.6 degrees Fahrenheit.
The conversion between PSI and inches of water is based on the weight of water. Specifically, 1 PSI is equivalent to approximately 27.68 inches of water column (inWC). This relationship allows engineers and scientists to easily convert pressure measurements from one unit to another.

P_{text{inWC}} = P_{text{PSI}} times 27.68
PinWC = pressure in inches of water column
PPSI = pressure in pounds per square inch
PPSI = pressure in pounds per square inch
