Again, not to say mixing by weight is wrong, but how can you rely on a kitchen balance that only reads to 0.01 g
to measure out 0.454 g. In my experience with scales, especially for milligram weight, an inexpensive kitchen scale won't be all that accurate. Now granted, if the scale is always off by the same amount on every weight, it probably won't matter for you (although it would to anyone trying to replicate your recipe by weight). But just because a scale "reads" 0.01 g does not mean it's accurate to 0.01 g, or 10 mg. Of course, if you're mixing say 250 ml at a time, it's probably fine, but for test batches of 5 ml, you would really require something quite accurate in that range.
Has anyone tried using a weight calibration set to determine how accurate those scales are? I guess I'm just used to using analytical scales that are quite a bit more expensive when working in the mg range.
