BMI Calculator - Calculate Your Body Mass Index

BMI or 'Body Mass Index' is an approximation of the body fat percentage (adipose tissue), using a height versus weight calculation. It is not an absolute accurate calculation, as body compositions can vary between individuals.

The BMI calculator relies on average body compositions to make the calculation and therefore the values can be misleading for some individuals. As an example, BMI is not accurate with extremely muscular bodies, as muscle is much heavier than fat and throws the calculation off.

If your body is of typical makeup for your weight, then BMI can be a very accurate calculation.
