I want to convert 1 kilogram to milligrams if you already know that one kilogram equals 1000 grams explain how knowing that one gram equals 1000 milligrams can help you
for each gram, there are 1000 milligrams. if there are 1000 grams and each of the 1000 grams are 1000 milligrams, you would have to do 1000 times 1000.
