Answer: 1.5 grams
Explanation: To convert 1,500 milligrams into grams, we use the conversion factor for milligrams and grams which is
1,000 milligrams = 1 gram.
Next, notice that we're going from a smaller unit, milligrams, to a larger unit, grams. Since we're going from a smaller unit to a larger unit, we divide the conversion factor. So we have 1,500 divided by the conversion factor, 1,000.
To divide 1,500 by 1,000, we simply move the decimal point in 1,500 3 places to the left to get 1.500 or 1.5.
So 1,500 milligrams equals 1.5 grams.
