Conversion Formula
The formula to convert wc to psi is: psi = wc * 0.00142233. This works because 1 water column (wc) equals 0.00142233 psi, a standard conversion factor based on the density of water and gravity’s effect. For example, multiplying 11 wc by 0.00142233 gives 0.01564663 psi.
Step-by-step math: 11 wc x 0.00142233 = 0.01564663 psi. Rounding to four decimal places results in 0.016 psi, which is the approximate conversion value.
Conversion Example
- Convert 5 wc to psi:
- Multiply 5 by 0.00142233.
- 5 x 0.00142233 = 0.00711165 psi.
- Rounded to 4 decimal points: 0.0071 psi.
- Convert 20 wc to psi:
- 20 x 0.00142233 = 0.0284466 psi.
- Rounded: 0.0284 psi.
- Convert 15 wc to psi:
- 15 x 0.00142233 = 0.02133495 psi.
- Rounded: 0.0213 psi.

Conversion Definitions
wc
Water column (wc) measures pressure based on the height of a water column that exerts force on a surface. It is used primarily in low-pressure systems like water supply and HVAC, where small pressure differences are significant, represented in units like inches or millimeters of water.
psi
Pounds per square inch (psi) is a pressure unit indicating how many pounds of force are applied over one square inch of area. It is used widely in tire pressure, hydraulic systems, and other engineering fields to quantify force exerted per area.
Conversion FAQs
Why is water column a preferred measurement in some systems?
Water column provides a simple way to measure small pressure differences in water systems, especially where precise control of water pressure is needed without the need for more complex instruments. It is easy to read and relates directly to water height.
How accurate is the conversion from wc to psi?
The conversion is highly accurate because it is based on a fixed, internationally recognized standard: 1 wc equals exactly 0.00142233 psi. This makes calculations reliable for engineering and technical purposes.
Can I use this conversion for gases or only liquids?
This conversion works accurately for liquids like water, where the density is known and consistent. For gases, pressure measurement involves different factors, and the water column measurement isn’t directly applicable without adjustments.
