The manual's specs are meaningless. It says 1 gram, .01 ounce, and .001
pound.

1 pound is ~454 grams; 1 ounce is ~28 grams. So the claimed resolution
fof .001 pound is roughly twice the 1 gram claim; the claimed resolution
of .01 ounce is roughly four times the 1 gram claim. Since the 1 gram
claim is emblazoned on the machine, I'd tend to believe that.

Those claimed resolutions simply tell you what the software is
interpreting the low-order bits of the analog-to-digital converter.

In any event, as any freshman science student can tell you, all of those
claimed resolutions are absolutely meaningless without knowing the
corresponding repeatability.

IOW, having one gram resolution doesn't mean much if three successive
weighings of the same item are, say, 101 grams, 107 grams, and 115 grams.
