How the conversion works
Multiply by 101,325 to go from atmosphere to pascal, 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? pascal to atmosphere — 1 Pa = 0.000009869232667 atm.
