What is body mass index formula? The body mass index (BMI) is a measure that uses your height and weight to estimate how much body fat you have. BMI can be use to screen for weight categories that may lead to health problems but it is not diagnostic of the body fatness or health of an individual. A high BMI can be an indicator of high body fatness. BMI does not measure body fat directly, but research has shown that BMI is moderately correlate with more direct measures of body fat, such as skinfold thickness measurements, bioelectrical impedance, underwater weighing, dual energy x-ray absorptiometry (DXA) and other methods 1-4.

What is Body Mass Index (BMI)?
Body mass index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women.
BMI is calculate by taking your weight in kilograms and dividing it by your height in meters square. For example, if you weigh 70 kg and are 1.75 m tall, your BMI would be 22.9.
A BMI of 25-29.9 is consider overweight, while a BMI of 30 or above is consider obese. However, BMI should be interpret with caution as it may not accurately reflect body fat in all cases, such as people who are very muscular or have a lot of bone mass.
If you’re concerned about your weight or Body Mass Index, speak to your doctor or a registered dietitian to get more information.
The BMI Formula
The BMI Formula is a calculation use to determine whether an individual is underweight, overweight, or obese. The formula takes into account an individual’s height and weight, and produces a number that represents their body mass index (BMI).
A person’s BMI can be interprete using different categories:
Underweight = <18.5
Normal weight = 18.5-24.9
Overweight = 25-29.9
Obese = ≥30
How to Calculate Your BMI
BMI, or body mass index, is a calculation that allows you to see if you are at a healthy weight for your height. It is not a perfect measure, as it does not take into account factors such as muscle mass, but it is a good place to start when trying to assess whether you are at a healthy weight.
To calculate your BMI, you will need to know your weight in kilograms and your height in metres. You can then use the following formula: BMI = kg/m2.
For example, if you weigh 70kg and are 1.6m tall, your BMI would be 22.5.
If you want to convert yourweight from pounds to kilograms, you can use the following conversion: 1kg = 2.2lbs. So, if you weigh 150lbs, that would be 68kg.
Once you have calculated your BMI, you can then compare it to the following BMI categories:
- Underweight: less than 18.5
- Healthy weight: 18.5-24.9
- Overweight: 25-29.9
- Obesity: 30 or above
What Your BMI Results Mean
Body mass index, or BMI, is a measure of body fat based on height and weight that applies to both adult men and women.
A BMI of 25 to 29.9 is considere overweight. A BMI of 30 or above is considere obese.
Overweight and obesity are risk factors for many chronic diseases, including heart disease, stroke, type 2 diabetes, and certain types of cancer.
Losing even a small amount of weight can reduce your risk for these diseases.
The Pros and Cons of Using BMI
There are a few different ways to calculate BMI, but the most common formula is weight in kilograms divide by height in metres square. BMI can be use to screen for weight categories that may lead to health problems, but it is not a diagnostic tool.
BMI has its pros and cons. One advantage is that it’s easy to calculate using only a person’s weight and height. Another pro is that BMI generally correlates with body fatness. A high BMI generally indicates higher levels of body fatness, and a low BMI generally indicates lower levels of body fatness.
However, there are also some disadvantages to using BMI. One disadvantage is that it doesn’t take into account where on the body fat is store. For example, someone with a high BMI but who carries most of their extra weight around their hips (an apple shape) may be at a lower risk for some health problems than someone with the same BMI who carries most of their extra weight around their waist (a pear shape).
Another downside to using BMI as a measure of health is that it doesn’t take into account muscle mass. Someone who is very muscular and has a high BMI may be healthier than someone. Who has a lower BMI but carries more body fat.
Overall, BMI can be a helpful tool for screening purposes, but it’s important to remember its limitations.
