The conversion of 11 wc to psi equals approximately 4.76 psi.
This means that when you take a pressure measurement of 11 water column units, it corresponds to about 4.76 pounds per square inch. The conversion involves multiplying the water column value by a factor based on the relation between water column height and psi, which makes it easier to switch between measurement systems.
Conversion Result and Explanation
11 wc converts to around 4.76 psi because 1 wc (water column) equals roughly 0.434 psi. To find the psi for 11 wc, multiply 11 by 0.434, resulting in 4.774 psi, rounded to two decimal places. This conversion helps in practical applications involving water pressure measurements in different units.

Conversion Formula
The formula to convert water column (wc) to psi (pounds per square inch) is based on the fact that 1 wc equals approximately 0.434 psi. It works because water’s density and gravity relate the height of water to pressure exerted. For example, 11 wc: 11 x 0.434 = 4.774 psi.
Calculation step-by-step: 11 wc x 0.434 psi/wc = 4.774 psi. This approach ensures that measurements in water column are accurately translated into psi, making it useful for engineering and plumbing contexts where precise pressure readings are needed.
Conversion Example
- Convert 5 wc to psi:
- Multiply 5 by 0.434: 5 x 0.434 = 2.17 psi.
- Result: 5 wc equals 2.17 psi.
- Convert 20 wc to psi:
- Multiply 20 by 0.434: 20 x 0.434 = 8.68 psi.
- Result: 20 wc equals 8.68 psi.
- Convert 15 wc to psi:
- Multiply 15 by 0.434: 15 x 0.434 = 6.51 psi.
- Result: 15 wc equals 6.51 psi.

Conversion Definitions
wc
Water column (wc) measures pressure as the height of a water column in units like inches or meters, indicating how high water can be pushed by pressure. It is used in water systems, HVAC, and engineering to gauge pressure levels based on water height.
psi
Pounds per square inch (psi) is a pressure unit indicating how many pounds of force are exerted on one square inch of area. It is common in tire pressure, hydraulics, and industrial applications to quantify pressure intensity.
Conversion FAQs
What does 11 wc mean in terms of water pressure?
11 wc represents the height of water in a column, which correlates to a pressure of about 4.76 psi. It describes how much force water exerts at that height, relevant in designing plumbing and water supply systems.
Is converting wc to psi accurate for high-pressure systems?
Yes, as long as the conversion factor (0.434) is used properly, the calculation remains accurate for most practical applications, including high-pressure scenarios, provided the measurements are correct.
Why is psi more commonly used than wc in some contexts?
Psi is more standard in many industries like automotive, HVAC, and hydraulics because it directly relates to force per area, making it more intuitive for certain engineering and safety calculations compared to water column units.
