Is there a simple formula that can be used?

the normal weight for a 5th grader is 103 pounds im a 6th grader and i only weidh 67 pounds so you should weigh more than 90 pounds
It has nothing to do with age. Height is directly correlated with weight as far as the human body is concerned. Of course, there is a difference whether you are male or female.
For example, if you're 5'5'' and 22 years of age, should you weigh more than 90lbs because you're over the age of 17? The older you get, you should weigh more? no.
If you're taller (5'11''), you should weigh more than you would if you were shorter (5'5'').
Go with the BMI index for best results.
you can compute your body mass index in this formula....
BMI= mass(lbs) x 703 / height(inches) / height (inches)
for example i am 123.45 lbs and 66 inches in height then i computed 19. 92.
a BMI of 18.5 to 25 may indicate optimal weight; a BMI lower than 18.5 suggests the person is underweight while a number above 25 may indicate the person is overweight; a BMI below 17.5 may indicate the person has anorexia nervosa or a related disorder; a number above 30 suggests the person is obese (over 40, morbidly obese).
it depends on how old you are (:
