BMI calculator

A BMI calculator assesses body weight relative to height to provide a Body Mass Index (BMI) value, which helps determine if a person has a healthy weight. BMI is calculated using the formula: weight in kilograms divided by height in meters squared. The resulting number classifies individuals into categories such as underweight, normal weight, overweight, or obese. While BMI is a useful screening tool for assessing weight-related health risks, it does not directly measure body fat or consider factors like muscle mass, age, or sex, so it should be used alongside other health assessments for accurate evaluations.
