## China 0-3 Years: Weight For Length Percentile

### Description:

This calculator is for ethnic Chinese children. This application is for newborns, babies and toddlers with an age of 0 to 3 years.

This calculator determines weight percentile based on length. Length is measured when the child is lying face upward (horizontal). The percentile shows how a child's weight compares to other children of the same length. The percentile reports the percentage of children that have a weight less than the measured child. For example out of a total group of 100 children, a percentile value of 55 percent means the child measures more than 55 children and measures less than the other 45 children.

A percentile of 50% represents the average weight. A percentile value below 50 percent means a child is less than average. A percentile value greater than 50 percent means a child is greater than average. Measurements outside of this range does not mean a child is underweight or overweight. A doctor should be consulted to determine growth status.

### Calculation Instructions:

1. Select Gender - Choose male for boys and female for girls.
2. Enter Weight - Mass of child.
3. Enter Length - Measured in the lying face upward position (horizontal).
