Q. How many centigrams are in 5 kilograms?
Two conversion factors are essential to solve this problem. Keep in mind that there are 1000 grams in a kilogram and 100 centigrams in a gram. To conclude the number of centigrams in 1 kilogram set up the first conversion factor so that kilograms cancel out. Place up the second conversion factor so that grams cancel out.
