BMI Calculator

Your BMI	Average BMI of  for people using this calculator

BMI or Body Mass Index is calculated by dividing your weight in kilograms by your height in metres squared. Remember - it is only a basic guide. If you are very sporty or muscular you may find that you fall into the 'overweight' classification on the BMI calculator (as muscle weighs more than fat), when in fact you are a healthy shape and have very little body fat. Also BMI is not accurate for people who are frail due to illness and muscle loss, or pregnant or breastfeeding women.
