Using simple, inexpensive materials, this balance is sensitive enough to weigh items of only a few milligrams, allowing you to find the approximate masses of objects and substances so light that they show no weight at all on ordinary kitchen or postal scales.
In the use of this balance, we’ll be dealing with mass, in grams. The distinction between weight and mass is critical in physics, but even in scientific settings it’s sometimes common to talk about “weighing” things on an analytical balance, rather than “massing” them. When that happens here, your forgiveness is appreciated!
