What is BMI Calculator?
A BMI Calculator helps you estimate your Body Mass Index using your height and weight. It is a quick way to understand whether your body weight falls into a healthy range.
BMI is commonly used as a general health indicator and can help identify if a person is underweight, normal weight, overweight, or obese.
How to Calculate BMI?
BMI is calculated by dividing your weight in kilograms by the square of your height in meters.
BMI Formula: BMI = weight (kg) / [height (m)]²
If you enter your weight in pounds or height in feet and inches, this calculator automatically converts them before calculating your BMI.
BMI Categories Explained
- Underweight: BMI below 18.5
- Normal Weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 or above
These ranges are widely used for general health screening and body weight classification.
What is a Healthy BMI Range?
A healthy BMI range is usually considered to be between 18.5 and 24.9. If your BMI falls within this range, it generally suggests a healthy body weight for your height.
Is BMI Accurate?
BMI is useful as a basic screening tool, but it does not directly measure body fat, muscle mass, or overall fitness. Athletes and muscular individuals may have a high BMI even if they are healthy.
BMI for Men and Women
The standard BMI formula is the same for both men and women, but body composition can differ. BMI is still useful for a general health estimate in both cases.
BMI Limitations
BMI does not account for muscle mass, age-related body changes, or fat distribution. It should be used as a general guide rather than a complete health diagnosis.
