Hm..the decimal point?

lets see...

12,321g (1kg/1000g)= 12.321kg

You can divide 12,321 by 1,000 on your calculator. What do you get?

Or -- since you're dividing by 1,000 which has has 3 zeroes, move the decimal point 3 places to the left.

Does your answer make sense? Would you expect the book to have more or less grams than kilograms?
