Another factor to take into account would be that of different populations and different body proportions. ![]() The obtained number can prompt one person into starting a weight loss diet as well as other restrains that might not reflect the general health condition of the body. There are also inaccuracies resulting from the fact that this index reflects the body mass versus surface and in the case of athletes, very muscular persons and even pregnant women, this cannot be accurate. There are separate tables for children but all adults are considered the same. There have been critics in time that referred to this original formula as not accurate as it doesn’t take into account the age for adults. In research BMI is used to analyze the risk of developing certain health conditions, especially those related with obesity such as type 2diabetes and coronary disease. It is a number that can quickly reflect whether one is in a healthy weight range or not. This weight index is used not only to assess the body mass condition but is also useful in dosing certain amounts of medicines to be taken. For the above example, at a height of 1.70 m the ideal weight is situated between 54 and 71 kg.įor other results the basic weight calculator will determine whether the result is in the underweight or overweight range and it will advise of the measures to be taken as well as indicated the healthy weight range for the input height. If it were to put these values to test we would receive not only the index value and the range but also a message in relation to that range and the ideal weight for a person of that height. Let’s take for instance the case of a female weighing 60 kg at a height of 1.70 m.Ī value of 20.8 is situated in the normal BMI range. The values obtained through the formula itself or the above weight tool can be found in the ranges of the BMI table based on the International Classification of WHO 2004. The conversions for the imperial measurement system are: 1 pound= 0.4535 kg, 1 inch= 0.0254 m. How to calculate BMI?Īs the body mass index calculates the mass per unit of surface area of the subject’s body it means that it is obtained through dividing the weight in kilograms by the square of the height in meters. It is used to classify underweight or overweight mainly in adults as children have adapted formulas. This is an indicator of the thinness or thickness of one’s body and has sparked a lot of controversy throughout the years since Adolphe Quelet first introduced it. This biological index takes account of both the weigh and height, the vertical length of the body, and then adjusts them in accordance to the sex of the tested subject. In order to understand what the body mass index refers to, we need to learn that the body mass is the scientific way to describe the weight in medical specialties. These are then put in the basic BMI formula that it discussed below to offer you a numeric result that will then place you in a certain body mass range. You are asked to input your weight, either in kg or in pounds and your height, either in meters or feet and inches and your gender. It is designed to assess your body condition based on three parameters. ![]() In order to come right in hand and not require any other applications, the calculator offers you the two main systems of measurement, metric and English and converts your values in the appropriate formula. This is a simple body mass evaluation tool that can quickly provide you with an indicator to where your weight stands and whether you can be classed as underweight, normal weight or in one of the three stages of obesity.
