The "grain" is an older method or measuring weight, from the outdated "apothecary" system of weight measurements. The "grain" was originally based on some agreed upon weight of a single grain of a certain plant (and therefore not universally reliable). However, you may still see the abbreviation "gr." on some medication bottles, next to or underneath the more modern equivalent in milligrams (mg). The modern equivalent is as follows: 1 grain = 65 mg (milligrams) (although 60 mg or 64.8 mg is sometimes used to equal "1 grain" for certain prescription medications). For non-prescription drugs such as Tylenol (acetaminophen) or aspirin: 1 grain = 65 mg therefore 2 grains = 130 mg
5 grains = 325 mg (one "regular strength" adult Tylenol or aspirin tablet in the USA) 10 grains = 650 mg A few other medications that have been around a long time, such as sodium bicarbonate tablets or phenobarbital tablets, are still still sometimes labeled with both mg and grain equivalents. These are simply hold-overs from decades ago when physicians wrote prescriptions using apothecary weight measurements. In modern healthcare, "grains" or "gr" as a measurement unit should never be used, for safety reasons. Measurement should be given in grams, milligrams, micrograms, or other appropriate metric measurement. Medication mistakes have happened because a physician's abbreviation of "gr" may be interpreted as either "gram" or "grain"... which are vastly different weight amounts!
325 mg for standard strength; 500 mg for extra strength
1 Grain of Aspirin = 65 mg.
5 Grains of Aspirin - 325 mg.
10 Grains of Aspirin = 650 mg.
1 grain= 65 mg and therefore 2 grains= 0.130 g
130mg
10 grains
There is one milligram in one milligram.
1 milligram is 0.0001 dekagrams.
1000mcg per milligram.
1 milligram = 1,000 micrograms 1 microgram = 0.001 milligram
1000 milligram equals a gram
How many micrograms (µg, ug or mcg) in a milligram(mg)? 1000 micrograms = 1 milligram, and 1000 milligrams = 1 gram.
1 micro-milligram = 0.000001 milligram 1,000,000 micro-milligrams = 1 milligram

1,000 micrograms (mcg) per milligram.
0.001 grams = 1 milligram
1mg is 1000mcg
1 milligram = 1 000 micrograms
