Calculate Your BMI
What Is Body Mass Index [BMI]
Your BMI is a measurement of your body weight based on your height and weight. Although your BMI does not actually “measure” your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person’s optimal weight depending on his height. Your BMI “number” will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.
The formulas to calculate BMI based on two of the most commonly used unit systems:
- BMI = weight(kg) / height(m) (Metric Units)
- BMI = 703·weight(lb) / height(in) (U.S. Units)
BMI Table for Adults
This is the World Health Organization’s (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older. The Body mass chart for adults and the body mass chart for children is different. This is because body mass index is accounted differently based on age and growth spurts. Here is the Body Mass Index Chart for women and for men that are 18 and older:
