Knowing your BMI is not so difficult, it only compares your weight to your height, and is calculated by dividing your weight (in kilograms) by your height (in meters squared). It only furnish you with an idea of whether you’re underweight, has a healthy weight, overweight, or obese for your height. BMI is one type of tool to help health professionals assess the risk of chronic disease, this article clearly explain how to know your BMI in kg.

 

Using a BMI calculator is one of the easiest and the most common ways to know if you are overweight or not, Most people probably have come across these although they may not know exactly how they work or what they are. It is very important that you understand what you are being told when you use one of these tools so that the results can be interpreted correctly.

 

A BMI calculator is simply known as a computer program that can be used to calculate the body mass index. This, of course, brings us to the question of the body mass index is? It can be said to be just a quick and easy way to determine if someone is overweight or not based on individual height and weight. The reason why both the height and the weight is used to determine the BMI instead of just the weight is simply to make sure that the difference between what is considered overweight for someone who is five feet tall is not the same for a person who is six feet tall.

 

Using a BMI calculator is pretty easy; all you really have to know is your weight in kg and your height in inches. These are the figures that needed to be entered into the BMI calculator, once that is done it will be processed by the computer and bring out the result. The actual formula to calculate the BMI is pretty simple in a situation where you simply prefer to work it out yourself, the formula for that will be revealed as you read on, I really don’t think it’s worth the stress doing the calculation manually since there are so many free BMI calculators online.

 

The results are usually given are number that ranges from between zero to fifty, sometimes it may be a bit higher than that if the person is significantly overweight but for most people, it’s usually between the range of twenty to thirty. Anything Number above twenty-five is actually considered to be overweight so it’s very important to have that in mind. Practically All BMI calculators have charts that are meant to help users interpret their results.

 

The first thing that you have to do if you are going to use a BMI calculator is to make sure that you understand just what you are calculating. It is simply a way to determine what your weight should be based on your height. Even then the results may not be all that accurate so don't put too much stock on them. It is, however, a useful way for most people to get an idea of whether or not they are overweight.

 

With your weight and your height numbers entered into the calculator, it will give you a number that represents your body mass index. Ideally, the number you get should be somewhere between twenty and thirty but most people will find that the number they get is higher than that.

 

It is important to understand that just because your body mass index is higher than the calculator says it should be done not necessarily mean that you are overweight. There are a couple of reasons that you may have gotten numbers that were not accurate. The first is probably because you have a lot of muscle, while the second being that you are tall. However, it is imperative to know that the numbers that are used by a BMI calculator were actually created over one hundred years ago and it was based on the ideal results for an average person.

 

 

 

The formula for calculating BMI:

Stated hereunder are the equations for calculating BMI in the International System of Units (SI) which gives the BMI in kg.

 

 

 

              

Ponderal Index

The Ponderal Index (PI) is somewhat similar to the BMI in that it’s used to measure the leanness or corpulence of a person on the account of their height and weight. The only major difference between the PI and BMI is the cubing rather than squaring of the height in the formula; check below for the formula. It is quite understandable that the BMI  is a  useful tool when considering large populations, it is not the same when it comes to determining leanness or corpulence in individuals. Although the PI suffers from similar considerations, the PI is more reliable to be used for relatively tall or short individuals, on the other hand, BMI tends to record uncharacteristically high or low body fat levels for the individual on the extreme ends of the height and weight spectrum. the equation below can be used for computing the PI of an individual using USC, using a 5'10", 160-pound individual as an example:

USC Units:

PI =       

SI, Metric Units:

 

 

 

 

 

0 to 18.5 - Underweight

 

18.5 to 24.9 - Normal

 

25-29.9 - Overweight

 

30 and Above - Obese

It is important to keep in mind when you are using a BMI calculator that it is not a definitive guide to whether you are overweight. It is used because it is a quick and easy way to make estimates based on large groups of people. For example, if you have a lot of muscle you will probably have a fairly high body mass index but not a lot of fat. It is therefore important that you only use the results that you get from the BMI calculator as a general guide.
