30 KG is about 67 lbs

Weight/Age calculator:

weight is in ratio to height not age my 11 year old sone is 5 foot 11 so he weighs alot more than 30kg, and its normal for kids this age to get little bit of weight gain cause they are getting ready for growth spurt, google height weight chart for best guide but if kid feels and looks okay, he is fine

idk, what is that in pounds? there's probably a chart for what weight you should be for your height and age, i'd google it

elzano what how is that the 30 what ever u call it lol

Im 11 and 135
