How the conversion works
Multiply by 133.3223874 to go from millimeter of mercury 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 millimeter of mercury — 1 Pa = 0.007500615758 mmHg.
