What is the formula for BMI?
Firstly you need to know your weight in kilograms, if you don’t have this measurement use a chart or simply divide your weight in pounds by 2.2 You then need to know your height in metres (divide inches by 39.4), then square this amount. Finally divide the first number by the second to find your BMI. Please note that the BMI calculation does not account for muscle mass, which is naturally heavier than fat, so if you are muscley the reading might be confusing, this is often the case with muscley males.
