Percentile Chart and Calculator

Health Care - Pediatrician - Pediatrics
This calculator provides your child's weight percentile
based on age. The percentile shows how your child's weight
compares to other children. The percentile tells you what
percentage of children weigh less than your child. For example
out of a sample of 100 children, a percentile value of 40
percent means your child weighs more than 40 children and
weighs less than the other 60.
A percentile of 50% represents the average or mean weight.
A value below 50 percent means a child weighs less than
the average. A value greater than 50 percent means a child
is above average. This does not mean your child is overweight
or underweight. A doctor or physician should be consulted
to determine weight status.
The calculator requires gender (male or female), birth date
of the child, adolescents or teenager and weight to entered.
