While the difference between 50.0024g and 50.0015g may not be significant, this same difference can become very significant during drug tapering that involves weighing amounts that are close to the lower end of what the scale can measure: A 20mg weight of powder could actually be as much as 20.4mg or as little as 19.5mg – which is already about a 5% difference in possible drug amounts before even making a cut. So when the scale reads 0.002g, the actual weight could be as high as 0.0024g or as low as 0.0015g, or anywhere from 2.4mg to 1.5mg.
