Body Mass Index (BMI)
Quickly measure and calculate your BMI
Body Mass Index (BMI) is a standardized formula to determine the ratio between height and weight. BMI is a fairly reliable indicator of body fat for most adults, though not for the elderly or those with a lot of muscle tone. It is best used to quickly categorize someone as underweight, normal weight, overweight, or obese.
