Minim, << MIHN uhm, >> is the smallest unit of fluid measure in the apothecaries’ system of measurement. Druggists once used this system, but they now measure many prescriptions in metric units. One minim equals 0.062 milliliter, or cubic centimeter. In the apothecaries’ system, 60 minims equals one fluid dram, and one fluid dram equals 1/8 of an ounce. One drop of liquid from a medicine dropper contains roughly one minim. The word minim comes from the Latin word minimus, meaning smallest.
