How to Convert PSF to cmH₂O
The pound per square foot and centimeter of water are both units of pressure. 1 centimeter of water equals 2.0481614362 psf. This means to convert psf to cmh₂o, you divide by 2.0481614362.
Formula
Step-by-Step Example
Convert 5 psf to cmh₂o:
We need to convert psf to cmh₂o
Since 1 cmH₂O = 2.0481614362 psf, divide by 2.0481614362
5 ÷ 2.0481614362 = 2.4412138182
5 psf = 2.4412138182 cmH₂O

About These Units
Pound per Square Foot (psf)
Pounds per square foot (psf or lbf/ft²) measures structural loads, wind pressure, and floor loading in US construction. Building codes specify floor loads in psf (residential: 40 psf, commercial: 50-100 psf). One psf equals approximately 47.88 Pascals.
Centimeter of Water (cmH₂O)
Centimeters of water (cmH₂O) measure low pressures in medical ventilators, CPAP machines (4-20 cmH₂O), HVAC systems, and manometers. One cmH₂O equals 98.07 Pascals. Based on the pressure exerted by a water column.
