Converting from Pound Per Square Foot (psf) to Inch of Water (inH₂0)

What is Pound Per Square Foot (psf)

Pound per square foot (psf) is a unit of pressure commonly used in engineering and construction to measure the pressure exerted on a surface per square foot.

What is Inch of Water (inH₂0)

Inch of water (inH₂0) is another unit of pressure often used in various industries, including HVAC and meteorology, to measure the pressure exerted by a column of water that is one inch in height.

Conversion Formulas

The default conversion between psf and inH₂0 is as follows:

• 1 psf = 0.1922216 inH₂0
• 1 inH₂0 = 5.20233 psf

Some other common conversions include:

• 2 psf = 0.3844431 inH₂0
• 2 inH₂0 = 10.40466 psf
• 3 psf = 0.5766647 inH₂0
• 3 inH₂0 = 15.60699 psf
• 17 psf = 3.267767 inH₂0
• 17 inH₂0 = 88.43961 psf

To convert from psf to inH₂0, you can use the formula:

Pressure in inH₂0=Pressure in psf×0.1922216

And to convert from inH₂0 to psf, use the formula:

Pressure in psf=Pressure in inH₂0×5.20233

Examples

• Convert 10 psf to inH₂0:

10 psf×0.1922216=1.922216 inH₂0

• Convert 5 inH₂0 to psf:

5 inH₂0×5.20233=26.01165 psf
