In order to compute whether an adult has over- or underweight the Body Mass Index, also called the Quetelet Index, can be used. This index is computed by dividing the square of your length by your weight.

To convert from feet to inches to cm you can add a computation in the input box: enter 6*12+5 if you are 6 feet and 5 inches.

Your weight:
Your height:
Your Body Mass Index:
.

If the index is below 18 then this is underweight. Overweight is the case if the index is above 25. There is statistical evidence that life expectation is shorter when the index is above 25 before the age of 40. If the index is above 30 then one is obese, losing weight is higly recommended, especially if there is much fat around your waist.

Losing weight is for most people very difficult. It means often more physical activity and eating less which is against our nature.
