BMI Calculator

ResultBMI = 22.96 kg/m^{2} (Normal)

The Body Mass Index (BMI) Calculator can be used to calculate your BMI value and weight status while taking your age into consideration. Use the "metric units" tab if you are more comfortable with the international standard metric units. The referenced weight range and calculation formula is listed below.
Reference
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.
Body Mass Index Formula
The formulas to calculate BMI based on two of the most commonly used unit systems:

BMI = weight(kg)/height^{2}(m^{2}) (Metric Units)
BMI = 703·weight(lb)/height^{2}(in^{2}) (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.
Category  BMI range  kg/m^{2} 
Severely underweight  < 16.5 
Underweight  16.5  18.5 
Normal  18.5  25 
Overweight  25  30 
Obese Class I  30  35 
Obese Class II  35  40 
Obese Class III  > 40

Ponderal Index
Similar to BMI, the Ponderal Index (PI) is a measure of leanness of a person. It was also called Rohrer's index. Comparatively, the Ponderal Index is more even for different stature. Therefore, it was commonly used in pediatrics.

PI = weight(kg)/height^{3}(m^{3}) (Metric Units)
