BMI calculator
Your body mass index (BMI) is the number that relates your body weight to your height. Your BMI number gives a general indication if your weight falls within a healthy range. It is the most widely used measurement for obesity. The score is valid for both men and women but it does have some limits as it may (a) overestimate body fat in athletes and others who have a muscular build and (b) it may underestimate body fat in older persons and others who have lost muscle mass. Why not calculate your Body Mass Index with our simple 40-step BMI calculator?
