BMI Calculator - What's Your Body Mass Index?

The BMI calculator is a beneficial tool that measures whether you are overweight, underweight, or ideal. Your weight alone is not enough to inform, as a tall, skinny male may easily weigh more than a rotund however short woman. The body mass index, or BMI, overcomes this issue by discovering a ratio of your weight to your height, and returning a single number. This number will suit a classification on the scale of BMI ranges, which are defined as underweight, normal, overweight, and overweight.

To exercise your body mass index on your own, and what the number means for you, you'll need to understand:

  • How to compute BMI.
  • What is normal BMI.
  • What the different BMI ranges are.

How to determine BMI

First, let's cover the estimation:

  • Divide your weight (in kgs) by your height (in meters).
  • Divide the answer by your height again to get your BMI.

So the body mass index formula is as follows:

BMI = weight/ height ².

Normal BMI

Our BMI calculator makes it a breeze for you to discover your number. However, please remember that BMI is a rough evaluation. The result can be rather deceiving for individuals who are well muscled (such as body contractors), or for those who have actually lost a significant quantity of muscle (such as the elderly).

If you are not sure whether or not you fall within the "normal" series of muscle mass, please think about utilizing among our more specific calculators. The body fat calculator can zero-in on your percentage of body fat, while our lean body mass calculator can inform you how much you would weigh with no fat.

BMI ranges

There are five basic ranges within the BMI scale:

  • Underweight = less than 18.5
  • Normal weight = 18.5 - 24.9
  • Overweight = 25 - 29.9
  • Obesity = 30 - 35
  • Severe obesity = 35 and more

The BMI Prime is an awesome modification to our own BMI calculator. It's a decimal number where 1.0 = the upper limit to the "normal BMI" variety. It's a super easy way to see if you're overweight or not. If your BMI Prime is more than 1, then you've got some weight to lose.
