BMI Calculator - What's Your Body Mass Index?

The BMI calculator is a helpful tool that measures whether you are overweight, underweight, or just right. Your weight alone is not enough to inform, as a high, skinny man might quickly weigh more than a short but rotund female. The body mass index, or BMI, overcomes this problem by discovering a ratio of your weight to your height, and returning a single number. This number will fit into a category on the scale of BMI ranges, which are defined as underweight, normal, overweight, and obese.

To work out your body mass index by yourself, and what the number means for you, you'll require to know:

  • How to compute BMI.

  • What is normal BMI.

  • What the different BMI ranges are.

How to compute BMI

First, let's cover the calculation:

  • 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 piece of cake for you to find your number. Nevertheless, please keep in mind that BMI is a rough evaluation. The outcome can be somewhat deceiving for individuals who are well muscled (such as body contractors), or for those who have actually lost a substantial amount of muscle (such as the senior).

If you are not sure whether you fall within the "normal" range of muscle mass, please think about using one of our more customized calculators. The body fat calculator can zero-in on your percentage of body fat, while our lean body mass calculator can tell you just how much you would weigh with no fat.

BMI ranges

There are 5 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 a nifty modification to our own BMI calculator. It's a decimal number where 1.0 = the upper limit to the "normal BMI" variety. It's an incredibly simple way to see if you're overweight or not. You've got some weight to lose if your BMI Prime is more than 1.
