Atmosphere (abbreviation: atm): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.
Pound Per Square Inch (abbreviations: psi, or lb/in2): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
How to Convert Atmospheres to Pounds Per Square Inches
Example: How many pounds per square inches are equivalent to 74.58 Atmospheres?
As;
1 Atmospheres = 14.69181 pounds per square inches
74.58 Atmospheres = Y pounds per square inches
Assuming Y is the answer, and by criss-cross principle;
Y equals 74.58 times 14.69181 over 1
(i.e.) Y = 74.58 * 14.69181 / 1 = 1095.7151898 pounds per square inches
Answer is: 1095.7151898 pounds per square inches are equivalent to 74.58 Atmospheres.
