Final answer:
The apothecary system is primarily used for measuring medications and is commonly used in the field of pharmacy. The units for weight in the apothecary system include grains (smallest unit) and stones (largest unit). The units for volume include minim (smallest unit) and barrel (largest unit).
Step-by-step explanation:
The apothecary system is primarily used for measuring medications and is commonly used in the field of pharmacy.
The units for weight in the apothecary system include grains (smallest unit), scruples, drams, ounces, pounds, and stones (largest unit). The units for volume include minim (smallest unit), fluidram, fluidounce, pint, quart, gallon, and barrel (largest unit). For example, in the apothecary system, 1 grain is equal to 64.79891 milligrams and 1 minim is equal to 0.05919 milliliters. Therefore, the apothecary system provides specific units of measure for precise medication dosing.
