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.
Atmosphere (abbreviation: atm): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.
How to Convert Pounds Per Square Inches to Atmospheres
Example: How many Atmospheres are equivalent to 89.72 pounds per square inches?
As;
1 pounds per square inches = 0.068065 Atmospheres
89.72 pounds per square inches = Y Atmospheres
Assuming Y is the answer, and by criss-cross principle;
Y equals 89.72 times 0.068065 over 1
(i.e.) Y = 89.72 * 0.068065 / 1 = 6.1067918 Atmospheres
Answer is: 6.1067918 Atmospheres are equivalent to 89.72 pounds per square inches.
