Body Mass Index
One first step to taking charge of your health is knowing your Body Mass Index. The term BMI is often used when discussing the obesity epidemic, but what is BMI? Use the Body Mass Index (BMI) Calculator to find which weight category your BMI matches
BMI stands for Body Mass Index. It is a number that shows body weight adjusted for height. BMI can be calculated with simple math using inches and pounds, or meters and kilograms. For adults aged 20 years or older, BMI falls into one of these categories: underweight, normal, overweight, or obese.
Obesity Cost Calculator
This calculator, created by the Centers for Disease Control and Prevention (CDC) uses input data provided by employer's human resources or benefits personnel to calculate an estimate of the costs to an organization that are obesity-related. With this information, employers can compare the costs and benefits of user-defined interventions targeted at reducing obesity. Click here to be redirected to the obesity cost calculator.
Smoking
In this country, lung disease is responsible for one in seven deaths. Quitting smoking not only "greatly reduces serious risks to your health" but it also can greatly increase your disposable income. Smokers in the US spend nearly $50 million annually on cigarettes. How much of that money did you kick in? Use the Cost of Smoking Calculator to determine how much you spend on cigarettes every week, month, and year--and how much you would save if you quit.
Live Stronger, Longer
The Living to 100 Life Expectancy Calculator© was designed to translate what we have learned from studies of centenarians and other longevity research into a practical and empowering tool for individuals to estimate their longevity potential.
BMI- Body Mass Index
So you have calculated your BMI and found which weight category your BMI matches. What does this all mean?
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:
- Eating Habits
- Physical Activity
- Waist Circumference
- Blood Pressure
- Blood Sugar Level
- Cholesterol Level
- Family History of disease
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.

Mathematical Formulas
If you are unable to use the BMI calculator, or if you are interested in how BMI is calculated, this page has the mathematical formulas. You can calculate BMI using either feet, inches, and pounds, or meters, centimeters, and kilograms.
English Formula
Body Mass Index can be calculated using pounds and inches with this equation
|
|
(Height in inches) x (Height in inches) |
|
For example, a person who weighs 220 pounds and is 6 feet 3 inches tall has a BMI of 27.5.
| ( |
(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 = |
(Height in Meters) x (Height in Meters) |
|
| or | ||
| BMI = ( |
(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.
|
(1.905 m) x (1.905 m) |
= 27.5 |
