🧠 What Is a BMI Calculator?
A BMI Calculator (Body Mass Index Calculator) is a quick and scientific way to measure whether your body weight is in a healthy range for your height.
It uses a simple formula:
BMI = weight (kg) ÷ [height (m)]²
This measurement helps you understand whether you are underweight, normal weight, overweight, or obese according to global health standards (like the World Health Organization).
BMI is not just a number — it’s a key health indicator that can help you identify risks linked to body weight, such as heart disease, diabetes, and hypertension.

📊 BMI Categories and What They Mean
Here’s a quick overview of how BMI is interpreted:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal (Healthy Weight) |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
If your BMI is too high or too low, consider consulting a healthcare professional for guidance.
Remember — BMI is a general guideline, not a diagnosis. It doesn’t measure muscle mass, bone density, or fat distribution.
🏋️ How Accurate Is BMI for Measuring Health?
While the BMI formula is widely used, it doesn’t tell the full story about your body composition.
For example, athletes or muscular individuals might have a high BMI but low body fat.
