If you take medications and need to determine each dose, a medical scale can be a big help! Pharmaceutical scales are designed to be incredibly precise, because just a small amount of medication can make a huge difference in its effectiveness.
Using a medical scale is also an easy way to figure out how many pills you have left. Simply weigh one, record the measurement and zero it out, then pour the rest of the pills into your weighing tray. Divide that larger measurement by the single pill weight, and you will know how many remain.
