We will have a automatic calculator on this page soon for the time-being here are the formulae...
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 |
Body Mass Index can also be calculated using kilograms and meters (or centimeters).
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 |
BMI is not the only indicator of health risk.
BMI is just one of many factors related to developing a chronic disease (such as heart disease, cancer, or diabetes). Other factors that may be important to look at when assessing your risk for chronic disease include:
- Diet
- Physical Activity
- Waist Circumference
- Blood Pressure
- Blood Sugar Level
- Cholesterol Level
- Family History of disease

Underweight |

Normal |
25.0 – 29.9 |

All persons who are obese or overweight should try not to gain additional weight. In addition, those who are obese or who are overweight with other risk factors should consider losing weight. A complete health assessment by a physician is the best way to decide the right steps for you.
Whatever your BMI, talk to your doctor to see if you are at an increased risk for disease and if you should lose weight. Even a small weight loss (just 10% of your current weight) may help to lower the risk of disease.
Physical activity and good nutrition are key factors in leading a healthy lifestyle and reducing risk for disease.
