Atmosphere (abbreviation: atm): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.
Pound Per Square Foot (abbreviations: psf, or lb/ft2): is a British (Imperial) and American pressure unit which is directly related to the psi pressure unit by a factor of 144 (1 sq ft = 12 in x 12 in = 144 sq in). Where, 1 pound per square foot equals 47.8803 pascals.
How to Convert Atmospheres to Pounds Per Square Feet
Example: How many pounds per square feet are equivalent to 15.15 Atmospheres?
As;
1 Atmospheres = 2115.6219939981 pounds per square feet
15.15 Atmospheres = Y pounds per square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 15.15 times 2115.6219939981 over 1
(i.e.) Y = 15.15 * 2115.6219939981 / 1 = 32051.673209071 pounds per square feet
Answer is: 32051.673209071 pounds per square feet are equivalent to 15.15 Atmospheres.
