Conversion Formula
The formula to convert wc to psi is: psi = wc × 0.03613. This works because 1 wc (water column) equals 0.03613 psi, a conversion derived from the physical relationship between water height and pressure. For example, 10 wc = 10 × 0.03613 = 0.3613 psi.
By multiplying the water column measurement by 0.03613, we shift from the height-based measurement to the force-based measurement in pounds per square inch, reflecting the pressure exerted by a water column of that height.
Conversion Example
- Convert 5 wc to psi:
- Multiply 5 by 0.03613
- 5 × 0.03613 = 0.18065 psi
- So, 5 wc = 0.18065 psi
- Convert 20 wc to psi:
- 20 × 0.03613 = 0.7226 psi
- Therefore, 20 wc = 0.7226 psi
- Convert 50 wc to psi:
- 50 × 0.03613 = 1.8065 psi
- Hence, 50 wc = 1.8065 psi
- Convert 100 wc to psi:
- 100 × 0.03613 = 3.613 psi
- Thus, 100 wc = 3.613 psi

Conversion Definitions
Water Column (wc)
Water column (wc) measures pressure based on the height of a water column that exerts a specific force on a surface, often used in HVAC and plumbing to indicate pressure levels in systems, representing how high water would need to be to exert that pressure.
Pounds per Square Inch (psi)
Psi (psi) is a unit of pressure that quantifies force per area, commonly used in the United States for tire pressure, fluid systems, and industrial measurements, representing pounds of force applied over one square inch of area.
Conversion FAQs
How accurate is converting wc to psi with the factor 0.03613?
The conversion factor 0.03613 provides a close approximation based on the physical properties of water at standard conditions, but minor variations may occur depending on temperature and fluid density, so for precise calculations, consider these factors.
Can I convert other water column measurements to psi using the same formula?
Yes, as long as the measurements are in wc units, multiplying by 0.03613 will give the pressure in psi, regardless of the height, as long as the water density remains consistent; for different fluids, the conversion factor would change.
Why do different pressure units matter in engineering?
Different units like wc and psi are used based on context; wc is common in HVAC and plumbing, while psi is standard in mechanical and industrial settings. Using the correct unit ensures safety, compliance, and accurate system performance assessment.
