How the conversion works
Multiply by 14.69594878 to go from atmosphere to pound per square inch, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? pound per square inch to atmosphere: 1 psi = 0.06804596391 atm.
