BMI Calculator

BMI Calculator - Body Mass Index

The BMI calculator is a valuable tool that lets you know if are overweight, underweight, or just right. Your weight alone is not enough to know, as an overweight, tall man is likely to weigh more women who are short, but not grouchy. BMI, also known as the body mass index also known as BMI is a solution to this issue by calculating the proportion of your weight to your height and then returning the same number. This number will fit into a specific category in the scale of BMIranges, which are defined as underweight normal, overweight as well as obese.

To work out how much body weight you weigh on your own and to understand what this number means 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 to calculate BMI

First, let's cover the calculations:

1. Divide your weight (in kgs) in relation to your height (in meters).
2. Divide the answer by your height once more to get your BMI.

Therefore, the body mass index formula is as the following:

BMI is weight/height2.

Normal BMI

Our BMI calculator makes it simple for you to figure out your exact BMI. Please note that BMI is a rough estimation. The result may be confusing for people who are strong (such as body builders) as well as for those who have lost significant amounts of muscle (such as the elderly).

If you're uncertain whether or not you are between an "normal" range of muscle mass, you should consider using one of our more specific calculators. Our body fat calculator will identify your proportion of body fat. In addition, our lean body mass calculator will reveal how much you'd weigh if you didn't have any fat.

BMI ranges

There are five primary areas within the BMI scale:

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

"BMI Prime" BMI Prime offers a useful variation to our BMI calculator. It's a decimal number where 1.0 is the upper limit to that "normal BMI" range. It's an easy way to find out if you're overweight or not. When your BMI Prime is more than 1, then you've got some pounds to lose.

Use our body mass index calculator

At the top of our BMI calculator, there are fields for you to input your dimensions and bodyweight. Enter these numbers then you'll see your BMI in addition to you'll get your BMI prime (see above) and a little message that will tell you which range you fall into.

If you're overweight and wish to know precisely how much weight you'll need lose to get into"the" healthyrange it is possible that you can do that as well. You can leave your height and weight in the boxes where they are and then type "0.9" into the BMI Prime box. Weight and BMI will adjust themselves.

Tip: If your height box is adjustable whenever you switch other boxes, you'll need to lock it. Click the right hand panel of the box, and then click the lock icon. This will hold this figure as you experiment with the numbers in the other boxes. That is... except if you plan on growing larger!

Other factors

If you're interested in knowing whether your metabolism is working in the pursuit of an healthy weight, then check our basal metabolic rate calculator (or its variant using the Harris-Benedict equation). There are many things that can be reported as increasing or decreasing our metabolism (which one does skipping breakfast results in?) We don't hear a lot about tracking these changes. This calculator is to track those changes.

Your basal metabolic level is the amount of activity you have in your body's metabolic rate when you get up in the early morning. That is when you are the most stable time for assessing your metabolism, as the day's heat hasn't had the chance to get warm!

If you've learned to calculate BMI, the next obvious number to consider is the ideal weight. Make use of our weight calculator that will help you figure this quickly.
