Body mass index (BMI) is a measure of body fat based on a person's weight and height.
To calculate BMI, you can use the following formula:
BMI = weight (in kilograms) / (height (in meters) x height (in meters))
Alternatively, you can use online calculators or charts that are readily available on the internet.
Here are the steps to calculate BMI manually:
-
Convert your weight from pounds to kilograms. You can do this by dividing your weight in pounds by 2.2.
-
Convert your height from inches to meters. You can do this by multiplying your height in inches by 0.0254.
-
Square your height in meters.
-
Divide your weight in kilograms by your squared height in meters.
The resulting number will be your BMI. The World Health Organization (WHO) classifies BMI into the following categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obesity: BMI of 30 or greater.
BMI formula
Body Mass Index (BMI) is a number that is calculated based on your height and weight. The outcome indicates whether you are at a good weight, or maybe underweight, overweight or obese. The BMI is suitable for the ‘average’ person. Exceptation for example is someone who does bodybuilding.
How do you calculate the body mass index? BMI is calculated by the following formula. The weight is divided by the square of the length. As an example we can take a person having a weight of 70 kg and a length of 175 cm. The calculation is 70 divided by the multiplication of 175cm. The outcome ……
There is underweight if the index is less than 18.5. The recommended weight we find in values between 18.6 and 24.9. There is obesity in values between 25.0 and 29.9. If there is an index greater than 30, then we call this obesity.
This calculation applies to men, women and children. For the interpretation of the BMI for children it is important to realise that they have other outcome. For example a boy at 7 years old a healthy BMI lays between 14 and 18.
The body mass index is used as a screening tool to bring potential health concerns However, it is not a diagnostic instrument. Studies to determine whether someone is at health risk, should always be performed by a medical specialist.
Use a BMI Chart or Body Mass Index Chart to find your healthy weight.
The BMI formula is used for men, women and children. For children there are other BMI values than for adults. For adults the Body Mass Index is based on your weight and height and it tells you whether you have a healthy body weight.
