1 psf = 0.000472541416041 atm

Show the working
  1. 1 psf = 0.000472541416041 atm
  2. 1 × 0.000472541416041 = 0.000472541416041 atm

How to convert pounds per square foot to standard atmospheres

1 psf = 0.000472541416041 atm, so multiply by 0.000472541416041 to go from pounds per square foot to standard atmospheres. Going the other way, 1 atm = 2,116.21662367 psf.

atm = psf × 0.000472541416041
psf = atm × 2,116.21662367

Worked example:

1 psf = 0.000472541416041 atm
5 × 0.000472541416041 = 0.0023627070802 atm
