Body Mass Index (BMI) is a popular tool used for health-related assessments across various healthcare centres. It is a measurement that incorporates a person’s body weight and height to calculate the total amount of body fat they have. Body Mass Index, alongside other tools, can assist health care providers in assessing an individual’s health-related risk factors and overall health condition. Its core calculation is based on the BMI formula, which involves dividing your weight (in kilograms) by the square of your height (in metres). Also, the BMI is one of the many tools that help healthcare providers classify weight type, which includes Underweight, Optimum Range, Overweight and Obesity (Class I, II and III). Even though it has some limitations, knowing and learning more about your BMI can help in leading a healthy lifestyle. To get a quick overview of your body mass index, make sure to use an online BMI calculator. You can find more details about body mass index, like BMI definition, its ideal range, calculation methods, reliability of the results, how to interpret the data, its relation with health insurance, etc., on this page.

BMI can be calculated with the help of two methods:International System of Units (SI) - BMI = weight (kg) ÷ (height (m))^2Imperial System - BMI = weight (lb) ÷ (height (inches))^ 2 × 703.
Right Range
Any number below or above the normal range is a cause for concern, and people should consult their doctors regarding the same
BMI Scale

BMI Formula
To calculate your BMI value, you need to know your weight in kilograms and your height in metres. If you know what your height is in centimetres, you can simply divide that number by 100. To calculate your BMI, you need to divide your weight in kilograms by your height in metres squared.
BMI = mass (kg)/height^2 (m)
If you know what your weight is in pounds and what your height is in inches, the BMI can be calculated as well. You need to divide your weight in pounds by your height in inches squared. You then need to multiply the amount by 703.
BMI = 703 x [mass (lbs)/height^2 (in)]
Interpretation: For adults 20 years old and older, BMI is interpreted using standard weight status categories. These categories are the same for men and women of all body types and ages.
BMI for Kids
A child’s body develops and changes quickly. This is why a standard adult BMI chart will not be appropriate. Hence, to keep track of whether your child is the correct weight for their height, doctors use another chart. They start with a standard BMI calculation based on your child’s height and weight. The BMI value is then used to determine how your child compares to other children of the same age and gender. This is done with the help of percentages and percentiles. The weight categories for children, based on percentiles, are:
Underweight – BMI less than the 5th percentile
Normal Weight – BMI above the 5th percentile but lower than the 85th percentile
Overweight – BMI above the 85th percentile but lower than the 95th percentile
Obese – BMI greater than or equal to the 95th percentile
Interpretation: For children and teens, the interpretation of BMI depends upon age and sex.

BMI values do have certain shortcomings when it comes to predicting future health issues. It only uses your height and weight and it does not take your body composition into account. So, the distribution of your muscle and bone mass might increase your BMI even if you’re healthy and not likely to suffer from weight-related health issues in the near future. Here are some of the limitations of using BMI for various age groups:
Adults
BMI is not accurate since it only measures excess body weight instead of excess body fat. So, it’s a good idea for adults to use BMI along with other measures to understand their potential health risks. The drawbacks of using BMI for adults include:
• Older adults will likely have more fat than younger individuals who have the same BMI.
• Women are more likely to have more body fat than men who have an equivalent BMI.
• Athletes and muscular people will probably have a higher BMI than others since they have large muscle mass.
Young Adults and Children
BMI cannot take into account a child’s growth rate and maturity. It can be used to identify obese children, but not overweight children as a slightly higher BMI could be caused by increased fat-free mass.

What people were most curious about
How do I calculate my BMI?
BMI or body mass index is calculated according to an individual’s weight and height. It is calculated by simply dividing your weight in kilograms by your height squared in metres. You can also find the results instantly by entering the height and weight data in HDFC ERGO’s BMI calculator.
What is the importance of BMI to understand a person’s health condition?
BMI helps to understand whether you fall in the healthy or unhealthy category and accordingly if you require any treatment or not. It helps you to keep a check on your health.
In India, do insurance companies ask for BMI?
Yes. Most insurers in India take into consideration an individual’s BMI to determine the premiums charged on health insurance and term insurance plans. A person with a high BMI is assumed to be a high-risk applicant and is charged higher premiums. People with a healthy BMI are charged relatively low premiums. Thus it is important that you keep tabs on your health by using a BMI calculator frequently.
Can one solely depend on BMI to determine if they need to loose or gain weight?
Knowing and checking your BMI regularly and working towards the ideal body weight ratio may help in your fitness journey. However, there are other factors that one needs to consider when we talk about body weight such as genetics, level of physical activity, age and sex, etc. Also, BMI cannot be applied, for instance, to athletes, pregnant women, elderly or young children. This is because the body mass index does not consider whether the weight is carried as muscle or fat. So, before you arrive at a conclusion, remember reaching a healthy weight isn't just about reaching a certain number on the scale or a certain BMI. Following healthy eating and exercise habits is very important and it is always better to seek a doctor’s opinion before you proceed to attain your ideal bodyweight.
