BMI Chart / Formula

Use the BMI Chart below to estimate your Body Mass Index. Simply slide the scale to your height and weight to see your BMI number change (you can also slide the scale to the weight you want to be -- a goal weight!). The BMI score means the following:

Underweight: Below 18.5 BMI

Normal: 18.5 - 24.9 BMI

Overweight: 25.0 - 29.9 BMI

Obesity: 30.0 and Above BMI





BMI Formula

English Formula

Body Mass Index can be calculated using pounds and inches with this equation

BMI = (             Weight in Pounds             
(Height in inches) x (Height in inches)		 ) x 703

For example, a person who weighs 220 pounds and is 6 feet 3 inches tall has a BMI of 27.5.

(             220 lbs.            
(75 inches) x (75 inches)		 ) x 703 = 27.5


Metric Formula

Body Mass Index can also be calculated using kilograms and meters (or centimeters).

BMI =             Weight in Kilograms             
(Height in Meters) x (Height in Meters)		  
  or  
BMI = (             Weight in Kilograms             
(Height in centimeters) x (Height in centimeters)		 ) x 10,000

For example, a person who weighs 99.79 Kilograms and is 1.905 Meters (190.50 centimeters) tall has a BMI of 27.5.

            99.79 Kg            
(1.905 m) x (1.905 m)		 = 27.5
