BMI (Body Mass Index) is an imperfect attempt to adjust weight by height, sex, and age. It does not calculate, for example, what percentage of body mass is muscle (as opposed to fat, bone, cartilage, and blood, among others). You can find a BMI calculator here:

But if you want a short answer, the average weight for 9-year-old boys is 61.6 lbs (28 kg), and for girls is 63.8 lb (29 kg). However, it may well be that they should be heavier (or lighter).
