A body mass index (BMI) calculator in kilograms (kg) and centimeters (cm) for children is a tool that estimates a child’s body fat based on their weight and height. For example, a BMI calculator can be used to determine if a child is underweight, overweight, or obese.
BMI calculators are important because they can help healthcare professionals assess a child’s growth and development. They can also be used to track changes in a child’s weight over time. The first BMI calculator was developed in the 1970s by Belgian statistician Adolphe Quetelet.
