lol I don't get the lbs/stone as well. It depends on your height. What is you body mass index? It is a very simple formula:
weigh (kg) / height ² (m²)
you just divide your weight by the square of your height.
example: A person is 160cm tall/60 kg, then her BMI is : [60 : (1,6 m)2 = 23,4]
If your weight is normal, the BMI should be between 18,5 and 25. However, you are 16 and not of age yet, which means it is not that bad if your slightly under or above this scale.
