Understanding BMI and Your Health

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on your weight in relation to your height. It's a simple screening tool that can indicate whether you're underweight, at a healthy weight, overweight, or obese.

How to Calculate

BMI is calculated by dividing your weight in kilograms by the square of your height in meters. Our calculator does this automatically for you, whether you use metric or imperial measurements.

BMI Categories

BMI values are categorized as follows: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). These ranges may vary slightly for different populations.

Limitations

While BMI is a useful screening tool, it doesn't directly measure body fat. It may not accurately reflect body composition for athletes, pregnant women, the elderly, or people with high muscle mass.
