Child Growth Context Calculator
Convert height and weight into a BMI figure with the age context that raw BMI hides.
A ten-year-old of 32 kg and 138 cm has a BMI of 16.8 against a rough reference midpoint of 18.5 for that age, and child BMI must be read against age and sex percentile charts rather than adult thresholds.
