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 90.99 Atmospheres?
As;
1 Atmospheres = 2115.6219939981 pounds per square feet
90.99 Atmospheres = Y pounds per square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 90.99 times 2115.6219939981 over 1
(i.e.) Y = 90.99 * 2115.6219939981 / 1 = 192500.44523389 pounds per square feet
Answer is: 192500.44523389 pounds per square feet are equivalent to 90.99 Atmospheres.
