Simple....
remember this:
King Henry Doesn't Usually Drink Chocolate Milk
Kilo- Hecto- Deka- Unit (Base) Deci- Centi- Milli-
(1000) (100) (10) (0.1) (0.01) (0.001)
Remember....when you're trying to convert if you're at decimeters..and you're going to centimeters..if you move the decimal to the right it's +1...or if it's to the left it's -1
This being said....
2.4 kg-----> cg
So you start at kilo- and move down to centi-....
which is 5 units...
2.4---->> move decimal 5 spots over....
240,000.00 centigrams.
Thus, your answer.
