Where Are You Right Now?

While the BMI calculator is not an effective tool for a detailed roadmap to achieving a weight management or health goal, it is a great way to see where you are on your journey when compared to the population average.

BMI doesn’t take into account body composition, so, if your Body Mass Index (BMI) seems high, but you have a muscular physique, don’t worry!

*Please note that this BMI Calculator measures the BMI for adults over the age of 18 only.

How much should I weigh?

When determining your ideal body weight, several factors should be considered. These include age, muscle-fat ratio, height, and bone density. Some people say your Body Mass Index (BMI) is the best way to calculate whether your body weight is ideal.

Others say BMI is faulty as it does not take into account muscle mass and suggest using a measurement of waist-hip ratio instead.

What is the formula for BMI?

The official formula for BMI was invented in the 1830’s by Belgian mathematician Lambert Adolphe Jacques Quetelet (1796-1874);

Metric BMI = ( weight (kg) / ( height (m)2 ) )

Imperial BMI = ( weight (lb) / ( height (in)2) ) x 703
