A BMI Index Calculator will help you estimate a healthy body weight based on how tall you are.

The Body Mass Index (BMI), or Quetelet index, is a statistical measurement which compares your weight and height.

It does not actually measure the percentage of body fat, but it’s a useful tool.

The Body Mass Index is defined as your body weight divided by the square of your height.

With the BMI calculator you don’t have to bother with the maths to find out what weight is preferable according to your height.

The Body Mass Index is a bit rough as an instrument. It doesn’t’ take into consideration if your weight comes from heavy muscles or just fat. But it does give you an indication if you should change your lifestyle to avoid putting your health at risk.
