Frequently Asked Questions

Common questions about BMI calculation

What is BMI and how is it calculated?

BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)². For imperial units: BMI = (weight in pounds × 703) / (height in inches)².

What are the BMI categories?

According to WHO standards: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30+). These categories help assess health risks associated with weight.

Is BMI accurate for everyone?

BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, or fat distribution. Athletes with high muscle mass may have higher BMI despite being healthy.

Can I track my BMI progress over time?

Yes! Our calculator automatically saves your BMI history in your browser's local storage. You can view your progress and clear the history anytime.

Should I consult a doctor based on my BMI?

BMI is a screening tool, not a diagnostic tool. If your BMI falls outside the normal range or you have health concerns, consult with a healthcare professional for personalized advice.
