Milligrams and grams are units of measurements used in the metric measurement system. There are 1000 milligrams in every gram. In order to figure out how many milligrams are in four grams, you must multiply the thousand milligrams times four. One thousand milligrams time four is equal to 4000 milligrams, thus 4000mgs is equivalent to 4 grams.
