To convert grams to milligrams, you multiply by what factor?

To convert grams to milligrams, you multiply by 1000 because there are 1000 milligrams in one gram. This relationship is based on the metric system, where the prefix 'milli' indicates a factor of one-thousandth (1/1000) of the base unit. Therefore, when you have a quantity in grams and want to express it in milligrams, you should multiply by 1000 to account for the conversion factor. For example, if you have 2 grams, multiplying by 1000 gives you 2000 milligrams. This foundational knowledge is essential in medication calculations to ensure accurate dosing and administration.
