What is BMI?
Body Mass Index (BMI) is a person’s weight in kilograms (or pounds) divided by the square of height in meters (or feet). A high BMI can indicate high body fat. BMI is only an estimate as it doesn’t take body composition into account.
Why Use the BMI Calculator?
BMI is a common measurement that estimates body fat using height and weight. It helps understand your health risks and whether your weight is in a healthy range. The BMI Calculator helps you understand your body composition and set better health goals.
How do I calculate my BMI index?
It is very easy to calculate Body Mass Index. The formula for calculating Body Mass Index (BMI) is mass/(height)^2 where mass is a person’s weight in kilograms and height is their height in metres squared.
How to use the tool to calculate BMI?
- Enter your weight and height using standard or metric measures.
- Click on “Calculate” and your BMI will appear below.
Understanding Your BMI Results
BMI= Weight (in kilograms) ÷ Height2 (in meters)
The BMI ranges are as follows:
BMI | Weight Status |
|---|---|
Below 18.5 | Underweight |
18.5 – 24.9 | Healthy Weight |
25.0 – 29.9 | Overweight |
30.0 and Above | Obesity |
For example, if a person weighs 70 kg and is 175 cm tall, their BMI would be:
BMI = 70 /(1.75)2 = 22.86
This places them in the "Healthy Weight" category.
Common Questions About BMI
Is BMI always accurate?
BMI is a general indicator of body fat, but it may not be accurate for everyone. Individuals with a lot of muscle mass, like athletes, may have a higher BMI without necessarily having excess body fat.
Can BMI be used for children and teens?
Yes, but the interpretation is different from that of adults. Child and teen BMI is calculated the same way, but the results are compared to those of other children of the same age and sex to determine weight status.
Does BMI take body frame size into account?
No, BMI does not take into account body frame size. It is a general measure that does not differentiate between bone, muscle, and fat.
Can you use BMI to track weight loss progress over time?
Yes. Your BMI should decrease as you lose weight, indicating a healthier weight status.
