What is the Birthweight Percentile Calculator & How does it work?
The birthweight percentile calculator is a tool used to determine the position of a baby’s birth weight in relation to other babies of the same gestational age. This helps healthcare providers assess whether a newborn is growing at an appropriate rate.
Percentiles are calculated based on large population studies that track the growth and development of infants over time. A percentile score indicates the percentage of babies with a lower birth weight than the baby in question.
P = frac{text{Number of Babies} < W}{text{Total Number of Babies}} times 100
