Question

Is there more than one million, less than one million or exactly one million milligrams in one kilogram. How do you know

Answer 1

There are exactly one million. There are 1000 milligrams per gram and 1000 grams per kilogram. Fine the number of milligrams in a kilogram by multiplying 1000x1000

Answer 2

There are exactly 1,000,000 mg (milligrams) in 1 kg (kilograms). I know because kilo means 1000. Milligrams are smaller than normal grams, and there are 1000 milligrams in 1 gram. So kilo is 1000 and 1 gram is also 1000 mg. If you multiply 1000x1000 you get 1,000,000.
