What is a BMI Calculator?

A BMI (Body Mass Index) calculator helps you assess whether your weight is within a healthy range for your height. It's a widely used screening tool to categorize weight status and potential health risks.

Why Use This Tool?

Understanding your BMI can help you monitor your weight, set health goals, and identify risks related to underweight or overweight conditions. It’s often used by individuals, fitness trainers, and healthcare professionals.

How It Works

You enter your height and weight, and the calculator uses a simple formula to determine your BMI value. Based on that number, it categorizes you into a weight status range (e.g., underweight, normal, overweight, obese).

Formula Used

The BMI is calculated differently depending on the measurement system:

Metric: BMI = weight (kg) / [height (m)]²

Imperial: BMI = (weight (lb) / [height (in)]²) × 703

The result is then matched against standard BMI categories defined by health organizations.

Who Can Use It?

This calculator is suitable for adults and teenagers. However, note that BMI does not account for muscle mass, body composition, or age/gender-specific differences, so it’s best used as a general guideline.
