## Body Mass Index (Reference Values)

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

Body Mass Index Categories:

< 18.5: Underweight

18.5-24.9: Normal Weight

25 – 29.9: Overweight

> 30: Obese

## Body Mass Index Calculation Formula in Feet

BMI = Weight (pounds) / height * height (inches) X 703

Steps for calculating Body Mass Index:

1.  My height is 5’7 feet.  I convert to inches, 5 feet x 12 + 7 = 67 inches
2.  I multiply my height in inches with itself: 67 *67 = 4489
3.  I divide my weight in pounds with the number I found above:
If I am 149 pounds I have: 149 / 4489 =0.03319
4.  I multiply this number with 703. So my BMI is 0.03319 * 703= 23.3
5.  23.3 is my Body Mass Index. In the reference values, I see that I am at Normal Weight

BMI is a purely indicative tool with a deviation in cases of athletes and people with increased muscle mass.
