BMI, or Body Mass Index, is a measure used to estimate a person's level of body fat based on their height and weight. It is commonly used as an indicator of whether an individual has a healthy body weight for their height. To calculate BMI, you divide a person's weight in kilograms by the square of their height in meters. The resulting number provides an estimate of their overall body composition. The formula is as follows: BMI = weight (kg) / height^2 (m^2) BMI is often represented as a single number, which is then categorized into different ranges to indicate whether a person is underweight, normal weight, overweight, or obese.
