Additionally, within the metric system, one gram is equivalent to 1,000 milligrams. Therefore, to convert kilograms to milligrams, you would first convert kilograms to grams and then grams to milligrams.

By multiplying:

1 kilogram = 1,000 grams 1,000 grams × 1,000 milligrams/gram = 1,000,000 milligrams

Thus, there are 1,000,000 milligrams in one kilogram, confirming that the correct answer is indeed 1,000,000 mg. This knowledge is fundamental in pharmacology and other health sciences where precise measurement is crucial.
