Body Mass Index (BMI) Calculator

 

Body mass index (BMI) is the best proxy for body fat percentage among ratios of weight and height. A frequent use of the BMI is to assess whether an individual's body weight is normal or desirable for a person of his or her height.

Body mass index (BMI) is categorized by the International Obesity Task Force as:

• 18.5–24.9 = Healthy weight,

• 25.0–29.9 = Overweight,

• 30.0–34.9 = Class I obesity,

• 35.0–39.9 = Class II obesity,

• >40.0 = Class III obesity.

It is generally acknowledged that obesity increases the risk of many diseases. These risks become more evident as the BMI increases.
