BMI Calculator - Body Mass Index

The BMI calculator is a valuable tool to determine if you are overweight, underweight, or just right. Your weight alone is not enough to determine this, since the tall and thin man is likely to weigh more women who are short, but not grouchy. The body mass index, also known as BMI can overcome this issue by calculating a ratio from your weight your height and calculating an exact number. The number you get will be a part of an appropriate category within the range of BMIranges which can be defined as underweight normal, overweight and overweight.

To determine your body mass index by yourself and to understand what this number will mean for you, have to know:

• How to calculate BMI.
• What's the normal BMI.
• What are the various BMI ranges are.

How do I calculate BMI

Then, let's go over the calculation:

1. Dividing your weight (in kgs) by your size (in feet).
2. Divide the answer by the height to determine your BMI.

So the body mass index formula is as follows:

BMI is weight / height2.

Normal BMI

Our BMI calculator makes it easy for you to find your number. But, remember that BMI is a rough estimation. The result could be untrue for people who are well muscled (such as body builders) as well as for those who have lost a significant amount of muscle (such those who are elderly).

If you're not sure whether or not your body is within your "normal" range of muscle mass, it is recommended to use one of our more precise calculators. A body fat calculation will zero-in on your percentage of body fat. In addition, using our calculator to calculate lean mass can reveal how much you'd weigh without fat.

BMI ranges

There are five fundamental ranges within the BMI scale:

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

It's called the BMI Prime offers a nifty adaptation to our BMI calculator. It's a decimal value where 1.0 = an upper limit for your "normal BMI" range. It's a simple way to know if you're overweight or not. If your BMI Prime is higher than 1, you've got some extra weight to shed.

Use our calculator to calculate the Body Mass Index

In the upper right-hand corner of our BMI calculator, there are fields for users to input their dimensions and bodyweight. Enter these numbers and you'll be able to instantly see your BMI and that is your BMI Prim (see above) along with a small message that will tell you which category you fall in.

If you're overweight , and you want to know exactly what amount you'll have to lose to get to"the" healthyrange If you want to know the exact amount you need to lose, you could do the same. Keep your weight and height in the boxes they are and then type "0.9" into the BMI Prime box. Both your weight and BMI will be adjusted automatically.

Tips: If your height box changes whenever you switch other boxes, you'll need to close it. The right hand side of the box and click the lock icon. This will secure that value in place while you alter the values in the other boxes. That is... not unless you plan on growing larger!

Other considerations

If you're interested in knowing whether your metabolism is working on the road to an healthy weight, you can use your basal metabolic rate calculater (or its variation with Harris-Benedict's formula). We frequently hear about factors altering our metabolism (which does skipping breakfast does again?) We don't hear a lot about tracking those changes. That's what this calculator is for.

The basal metabolic rate of your body is the level of activity in your body's metabolism at the time you first wake up in the morning. It is also the most reliable time of the day to gauge your metabolism since the day's heat hasn't had the chance to warm you up!

Once you know how you can calculate BMI, the next obvious number to consider is the ideal weight. Use our perfect weight calculator and figure this out quickly.
