A182 uses inch-pound units, A182M uses SI (metric) units. They are identical in all other aspects.

The suffix M means the standard is in metric version.

And you need to know which to work to, the values are not exactly the same and the tolerances are slightly different. Conversion can get you into a lot of trouble.
