Body Mass Index

Your BMI is calculated by dividing your weight (in kilograms) by the square of your height (in meters). In other words the algebraic expression for BMI is kilograms per square meter:

BMI = Kg / (m)2

One variable BMI fails to consider is lean body mass. It is possible for a healthy, muscular individual with very low body fat to be classified obese using the BMI formula.

Enter your height (in inches) and weight (in pounds) in the boxes below and then click "Calculate." The following conversion factors are used in the metric to english calculations:

 1 inch = 2.54 cm 100 cm = 1 m 1 lb = 0.45359237 Kg

 Height: Inches Weight: Pounds

Now refer to the BMI table to see where you are...

If your BMI is below 20: Under Weight

If you are not an athlete, a lean BMI can indicate that your weight may be too low, which may lower your immunity. If your BMI and body weight are low, you should consider gaining weight through good diet and exercise habits, to increase your muscle mass.

If your BMI is between 20 and 22: Heralthy Weight

This indicates the ideal, healthy amount of body fat, which is associated with living longest, and the lowest incidence of serious illness. Coincidentally, it seems this ratio is what many individuals perceive to be the most aesthetically attractive.

If your BMI is between 22 and 25: Healthy Weight

This is still considered an acceptable range, and is associated with good health.

If your BMI is between 25 and 30: Overweight

You are considered overweight and should finds ways to lower your weight, through diet and exercise. You are at increased risk for a variety of illnesses at your present weight. You should lose weight by changing your diet and exercising more.

If your BMI is over 40: Dangerously Overweight

A BMI over 40 is dangerously overweight and puts you at severe risk of heart disease, diabetes, high blood pressure, gall bladder disease, circulation problems, and some cancers. Losing some weight could save your life.
