BMI Calculator

BMI Calculator - Body Mass Index

The BMI calculator is a useful tool that measures whether you are overweight, underweight, or just right. Your weight alone is not enough to know, as tall, thin men can easily weigh more than a short but rotund woman. A body mass index also known as BMI can overcome this problem by finding a ratio from your weight height, and returning only one number. This number will fit into an area on the scale of BMIranges, which are defined as underweight normal, overweight, and obese.

To determine your BMI on your own, and what the number is for you, you'll be required to know:

• How do I calculate BMI.
• How do you define normal BMI.
• What the various BMI ranges are.

How do you calculate BMI

First, let's cover the equation:

1. You can divide the weight (in kgs) per your size (in feet).
2. Divide the answer by your height once more to calculate your BMI.

Therefore, the formula for the body mass index is as follows:

BMI is weight/height2.

Normal BMI

Our BMI calculator is simple to determine your number. But, remember that BMI is a rough estimate. The results can be confusing for people who are strong (such as bodybuilders) or who have lost significant quantities of muscle (such as the elderly).

If you're uncertain whether or not you are inside the "normal" range of muscle mass, please consider using one of our more accurate calculators. Body fat calculator is able to pinpoint your percentage of body fat, and the lean mass calculator will show you what your weight would be without fat.

BMI ranges

There are five fundamental areas within the BMI scale:

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

"BMI Prime" BMI Prime can be described as a handy variation to our BMI calculator. It's a decimal digit where 1.0 = an upper limit for what is known as the "normal BMI" range. It's an easy way to find out if you're overweight or not. In the event that your BMI Prime is higher than 1, then you've got some weight to lose.

Using the body mass index calculator on our site

On the top of our BMI calculator are fields that allow you to input your size and weight. Add these values and you'll get your BMI and the BMI (see above) (see above) and a little message telling you what is the range that you fall into.

If you're overweight , and you want to know precisely what you'll need to shed to be in"the" healthyrange You can do that too. You can leave your height and weight in the boxes as they are. Type "0.9" into the BMI Prime box. The weight you put in and BMI will adjust themselves.

Tip: If the height of your box is adjustable in response to changes in other boxes, you'll be required to secure it. Just click the right hand panel of the box. Click the lock icon to hold that number in place as you experiment with the numbers in other boxes. That is... until you're planning on growing larger!

Other considerations

If you're looking to find out if your metabolism is working for you on the road to a healthy weight, then check your basal metabolic rate calculater (or its variant using Harris-Benedict formula). It's common to hear about events that can affect our metabolism (which one is skipping breakfast? do again?) We don't hear a lot about monitoring those changes. That's what this calculator is to track those changes.

Your basal metabolic rate refers to the level of activity in your body's metabolism at the time you get up in the early morning. The most reliable time of the day to measure metabolism, since it's too early to get you warm yet!

Once you have figured out how you can calculate BMI, the next important figure to be aware of is the ideal weight. Use the ideal calculator for weight to work this out in a jiffy.
