How the conversion works
Multiply by 0.06804596391 to go from pound per square inch to atmosphere, 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? atmosphere to pound per square inch — 1 atm = 14.69594878 psi.
