The BMI calculator is a helpful tool that determines whether you are overweight, underweight, or perfect. Your weight alone is inadequate to inform, as a tall, slim male might quickly weigh more than a rotund but brief female. The body mass index, or BMI, overcomes this problem by finding a ratio of your weight to your height, and returning a single number. This number will suit a category on the scale of BMI ranges, which are specified as underweight, normal, overweight, and obese.
To work out your body mass index on your own, and what the number implies for you, you'll need to understand:
- How to determine BMI.
- What is normal BMI.
- What the numerous BMI ranges are.
How to calculate BMI
Initially, let's cover the computation:
- Divide your weight (in kilograms) by your height (in meters).
- Divide the answer by your height once 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 discover your number. However, please bear in mind that BMI is a rough estimate. The outcome can be somewhat misguiding for individuals who are well muscled (such as body builders), or for those who have lost a considerable amount of muscle (such as the elderly).
If you are unsure whether you fall within the "normal" variety of muscle mass, please think about using among our more specialized 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 fundamental 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 cool adjustment to our own BMI calculator. It's a decimal number where 1.0 = the upper limit to the "normal BMI" variety. It's a very simple method to see if you're overweight or not. If your BMI Prime is more than 1, then you've got some weight to lose.
