This is completely incapable of measuring individual milligrams. Just because it claims to and shows a digit for it doesn’t mean it can.

Even $500 analytical balances like [0] can struggle with 1mg resolution, but I’d trust them a lot more. Generally you need to throw away the least significant digit of precision with digital scales.

The request may have been misguided. They don't need a milligram accurate scale. They're actually wondering how to taper a 10mg doses drug, which is actually comprised of a much higher than 10mg pill, more like 100 to 200mg. The rest is typically binder.

Also, note that while your $500 scale may be necessary for absolute accuracy, splitting 10mg is not the same as finding exactly 10mg.
