kPa to psf Converter (Kilopascals to Pounds/ft²)
Convert European EN 1991 occupancy live loads, wind pressures, and geotechnical bearing pressures from kPa to US Customary psf.
kPa to psf Conversion Formula
To convert any value in Kilopascal (kN/m²) (kPa) to Pounds per Square Foot (lb/ft²) (psf), multiply the quantity by the exact factor 20.88543423.

Structural Engineering Application
Soil investigation reports from international geotechnical consultants report allowable soil bearing in kPa. Structural engineers designing shallow footings in US units convert to psf (or tsf).
Common Conversion Mistake
Forgetting that 1 tsf (ton per square foot) = 2,000 psf. 100 kPa is approximately 2,088 psf, or roughly 1.04 tsf.
