2. • The body mass index (BMI) uses height
and weight in a mathematical formula to
determine a child's weight status
compared with other children. BMI does
not measure body fat.
• To calculate your child's BMI, please use
one of the following equations:
3. • If you know your child's weight and height
in kilograms and meters, BMI = weight in
kilograms divided by (height in meters
times itself). Follow these steps to
calculate your child's BMI.
4. • 1) Multiply your child's height in meters
by his or her height in meters. For
example, if your child is 1.24 m tall, 1.24 x
1.24 = 1.5376.
• 2) Divide your child's weight in kilograms
by the answer you got in step 1. For
example, if your child weighs 25 kg, divide
25 by 1.5376. The answer is 16.259105
• 3) The number you get is your child's
BMI. Round it off to one decimal place. In
the example, the child's BMI would be
16.3.
5. • If you know your child's weight and
height in pounds and inches, BMI =
(weight in pounds times 703) divided by
(height in inches times itself).
• Follow these steps to calculate your
child's BMI.
6. • 1) Convert ounces of weight and fractions
of inches into decimals. For example, if
your child weighs 35 lb and 8 oz, 8 oz
would be 0.5 lb and you would use 35.5 lb
as your child's weight.
• 2) Multiply your child's height in inches
by his or her height in inches. For
example, if your child is 39.75 in., 39.75 x
39.75 = 1,580.0625
7. • 3) Multiply your child's weight by 703.
For example, if your child weighs 35.5 lb,
35.5 x 703 = 24,956.5.
• 4) Divide the answer in step 3 by the
answer in step 2. In the example, divide
24,956.5 by 1,580.0625 = 15.794628.
• 5) The number you get is your child's
BMI. Round it off to one decimal place.
In the example, the child's BMI would
be 15.8.
8. • Overweight
• Depending on age and height, boys are
considered overweight if their BMI is more
than 30. For girls, a BMI of more than 32 is
considered overweight.
• Underweight
• Depending on age and height, boys are
considered underweight if their BMI is
less than 14. For girls, a BMI of less than
13 is considered underweight.
