How the conversion works
Multiply by 9.869232667 to go from megapascal 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 megapascal: 1 atm = 0.101325 MPa.
