BMI Calculator - Body Mass Index

The BMI calculator is a helpful tool that lets you know if are obese, underweight, or just right. Your weight alone isn't enough to know, as an overweight, tall man might weigh more than women who are short, but not grouchy. A body mass index or BMI can solve this problem by determining a ratio of your weight to your height and then returning the same number. This number can be classified into a category on the scale of BMIranges which are classified as underweight normal, overweight, and obese.

To calculate your BMI on your own and determine what it signifies for you, you'll need to know:

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

How do you calculate BMI

Then, let's go over the calculation:

1. Then divide your body weight (in kgs) with your tallness (in metres).
2. Divide the result by your height again to calculate your BMI.

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

BMI is weight / height2.

Normal BMI

Our BMI calculator is easy for you to figure out your number. Be aware that BMI is an approximate estimate. The result can be somewhat incorrect for those who are muscly (such as bodybuilders) as well as for those who have lost significant amounts of muscle (such as the elderly).

If you are unsure whether or not you are in an "normal" range of muscle mass, it is recommended to use one of our more accurate calculators. Our body fat calculator can find your percentage of body fat, and our lean body mass calculator will reveal how much you'd weigh with no fat.

BMI ranges

There are five basic intervals in the BMI scale:

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

It's called the BMI Prime can be described as a useful enhancement to our BMI calculator. It's a decimal value where 1.0 = an upper limit for the "normal BMI" range. It's an easy way to know if you're overweight or not. If you're BMI Prime is more than 1, you've got some weight to shed.

Making use of the body mass index calculator on our site

At the top of the BMI calculator are fields for you to input your size and weight. Input these numbers and you'll be able to instantly see your BMI the same as you'll get your BMI Premier (see above) as well as a brief message that will tell you which category you fall in.

If you're overweight and want to know precisely the amount you'll need lose in order to reach that healthyrange, you could do the same. You can leave your height and weight in the boxes they are and then type "0.9" into the BMI Prime box. Both your weight and BMI will adjust themselves.

Tip: If your height box changes as you alter other boxes, then you'll need to secure it. Just click the right hand panel of the box and select the lock icon. It will keep the figure while you play around with the figures in the other boxes. That's... not unless you are planning on getting taller!

Other aspects to consider

If you're curious to find out if your metabolism is in your favor to achieve an healthy weight, check out using our calculator for basal metabolic rates (or its version with Harris-Benedict's equation). There are many things that can be reported as which can increase or decrease our metabolism (which do skipping breakfast results in?) However, we don't hear much about analyzing the effects of these changes. This calculator is for.

Your basal metabolic level is the amount of activity you have in your body's metabolic rate when you first wake up in the early morning. This is the most reliable time of the day to determine your metabolic rate, because the day's not had enough time to warm you up!

When you've figured out how to calculate BMI, the next sensible figure to look up is your ideal weight. Make use of this ideal tool to find it out in a snap.
