You are using units of length not pressure.

There are actually 2 standards, most dive guages (to meet CE requirements ) are calibrated to the european standard
The actual defination is..

10 m of salt water having a specifig gravity of 1.01972 is 1.00 bar


for comparison
the us NAVY assigns a specific gravity 1.02480 so 1atm = 33.066 fsw, which is normally refined to 33.00 fsw

so depending on which defination you use the conversion fsw to msw is

for 33.066 is 3.2633 fsw/msw
or
for 33.000 is 3.2568 fsw/msw
