What is BMI?

Your Body Mass Index (BMI) can tell you if you are Healthy Weight Range.

It is important to remember that a BMI Calculation is not perfect as it does not take into account age, people less than 5 feet, muscular builds and pregnant woman.

Matthews Calorie Counter does not use your BMI in any of your weight loss calculations. Your BMI is just a ballpark figure and should not be used to determine whether you are healthy or not, only your doctor can determine that.



How to Calculate BMI?

Step 1. Convert your Height and Weight into Inches and Pounds.

Step 2. Using this BMI Formula, calculate your BMI: ( Weight / ( Height * Hieght ) ) * 703 = BMI

*For a metric version, please see our Metric BMI Calculator
