What is BMI?
The range that is considered "normal" or healthy weight depends upon a person's height. It is natural for taller people to weigh more. BMI stands for Body Mass Index. It is a number that is calculated based on both the height and weight to determine if the weight is high or low compared with what you would expect for that height. BMI indicator of body fatness, and is used as a screening tool for weight issues.
How to Calculate BMI
BMI = W / (H2) where W is the person's weight (in kilograms, not pounds) and H is the person's height (in meters). In other words, BMI is a person's weight (in kilograms) divided by the square of height (in meters).
If weight is in pounds and height is in inches, then BMI is calculated using a similar formula, only multiplying by 703. i.e., 703 * W / (H2), where W is the weight in lbs and H is the height in inches.
An easier way to find out your BMI is to use a BMI calculator or look up this reference table or the chart below.
