Show the working
  1. 1 psf = 0.0478802589803 kPa
  2. 1 × 0.0478802589803 = 0.0478802589803 kPa

How to convert pounds per square foot to kilopascals

1 psf = 0.0478802589803 kPa, so multiply by 0.0478802589803 to go from pounds per square foot to kilopascals. Going the other way, 1 kPa = 20.8854342332 psf.

kPa = psf × 0.0478802589803
psf = kPa × 20.8854342332

Worked example:

1 psf = 0.0478802589803 kPa
5 × 0.0478802589803 = 0.239401294902 kPa
