Converting from One Measurement System to Another You will have to convert from one measurement system to another when the doctor's order, for example, orders a medication in terms of grains (gr) and you have the medication but it is measured in terms of milligrams (mg). In this case, you will have to mathematically convert the gr into mg. The table below shows conversion equivalents among the metric, apothecary and household measurement systems. Conversions Among the Systems of Measurement METRIC APOTHECARY HOUSEHOLD 1 milliliter 15 minims 15 drops (*different once using IV tubing 5 milliliters 1 fluid dram 1 teaspoon or 60 15 milliliters uid drams 1 tablespoon or 3 teaspoons 30 milliliters 8 fluid drams or 1 fluid ounce 2 tablespoons 1 glass (unless specified 180 milliliters 6 fluid ounces differently) 240 milliliters 8 fluid ounces or 12 pint 1 cup 480 milliliters 1 pint 2 cups 1 liter 32 fluid ounces or 1 quart 4 cups or 1 quart 1 milligram 1/60 grain 60 milligrams (** 65 mg) grain 300-325 milligrams (depends on 5 grains med, see below * *) 1 gram 15-16 grains 2.2 pounds 1 kilogram * IV tubing has its own number of drops per ml (drop factor): typically 10 drops (gtt), 15 gtt, 20 gtt, or 60 gtt * * Grains are used for a limited number of medications. For Tylenol, Aspirin (ASA), and Iron (FE) 65 mg = gr l (one grain)
