Understanding Your BMI Calculator Results

Body Mass Index (BMI) is a simple calculation that provides a useful measure of whether you're at a healthy weight for your height. Our BMI calculator uses the standard formula: weight (kg) divided by height (m) squared, or BMI = kg/m².

BMI Calculator Categories and Ranges

Underweight Below 18.5
Normal Weight 18.5 - 24.9
Overweight 25.0 - 29.9
Obese 30.0 and above

How to Use This BMI Calculator

Using our BMI calculator is straightforward. Simply enter your current weight and height using either metric (kilograms and centimeters) or imperial (pounds and feet/inches) measurements. The calculator will instantly compute your BMI and display your category.

For example, if you're 170 cm tall and weigh 70 kg, your BMI would be 24.2, placing you in the normal weight category. The BMI calculator provides immediate feedback to help you understand your current health status.

BMI Calculator Limitations

While this BMI calculator is a useful screening tool, it's important to understand its limitations. BMI doesn't distinguish between muscle and fat mass, so athletes with high muscle mass might be classified as overweight despite being very healthy. Additionally, BMI calculations don't account for age, sex, or bone density differences.

Tips for Maintaining a Healthy BMI

If your BMI calculator results show you're outside the normal range, consider consulting with a healthcare professional. They can provide personalized advice based on your complete health picture, not just your BMI calculation. Regular exercise, balanced nutrition, and lifestyle modifications can help you achieve and maintain a healthy BMI over time.
