Calculate your BMI
Choose the tab for either Imperial (stones, pounds, feet and inches) or Metric (Kg and cm), enter you measurements and we'll calculate your BMI.
How to calculate your BMI
Body Mass Index, or BMI, is a measure of weight relative to height. To calculate your BMI, divide your weight (kg) by your height (m) squared.
A slightly easier way to do this using a calculator: enter your weight in (kg), divide it by your height (m) and then divide it by your height (m) again. If the answer is not 15-40 start again – a common mistake is to use cm instead of m or do the sum the wrong way around.
The resultant score is used to classify your health risk, see the graph below. If you fall into the obese category, it places you at a high risk of developing health complications.
The higher your BMI, the higher your health risk
Research suggests that health risk increases exponentially beyond a BMI of 30. At this height to weight ratio a person is classified 'clinically obese' and is considered to have a high risk of developing chronic diseases such as liver and heart problems, Diabetes, high blood pressure and Osteoarthritis.
The BMI is a useful tool for measuring health risk, however accurate classification of your health risk requires a holistic assessment by a health professional.
Our doctors will measure your waist to hip ratio (fat around your abdomen carries a greater health risk than fat around your waist), discuss your lifestyle and may perform a Bioelectrical Impedance Analysis to determine the amount of fat and muscle in your body.
If you are concerned about your BMI don't despair. We recommend making an appointment with one of our doctors to discuss your health status and risks.
