What is Body Fat?


A person's body fat percentage is the weight of the person's fat divided by the person's total weight expressed as a percentage.

There are various methods of measuring body fat percentage. Many of those methods require special equipment. However, there are some methods that can approximately calculate the body fat percentage using body's weight and circumference measurements at various points of the body. Such methods are frequently used by US armed forces. We use one such method in this calculator.


Select your gender. If you are a male, then enter your weight and your waist measurement. If you are a female, then enter your weight, waist, wrist, forearm and hip measurements. Press "Calculate" button. You will see your body fat percentage.

For example, if you are a female and enter your weight as 60 Kg., your waist as 30 inches, your wrist as 7 inches, your forearm as 8 inches and your hip as 36 inches, then your body fat percentage will be shown as 15%.


As per the guidelines of American Council for Exercise, a body fat percentage of up to 31% is considered as acceptable for women and up to 24% is considered acceptable for men. A higher value is considered as an indicator of obesity.

The body fat percentage calculated by this tool is just an approximation. If you are interested in a more accurate measurement of body fat percentage, please consult your health care provider. The interpretation of the body fat percentage given above is for information purpose only and should not be considered as medical advice.
