What is BMI?
BMI stands for Body Mass Index. It is a numerical value derived from your weight (in kilograms) and height (in meters) and is used to categorize individuals into health ranges, such as underweight, normal weight, overweight, or obese.
Why Use a BMI Calculator?
✅ Quick and Easy
No complex formulas—just enter your weight and height, and the result is calculated instantly.
✅ Accurate Classification
BMI classifies your body type based on international health standards from organizations like the WHO.
✅ Supports Health Awareness
It offers a first look at whether your body composition might put you at risk of chronic diseases.
✅ Works for All Ages (Adults)
Though BMI isn’t a diagnostic tool, it’s useful for screening potential health issues in adults.
How to Use the BMI Calculator
- Enter your height in centimeters (e.g., 170 cm)
- Enter your weight in kilograms (e.g., 65 kg)
- Click “Calculate BMI”
- Instantly see your BMI value and its health category
Example:
- Height: 170 cm
- Weight: 65 kg
- BMI = 65 / (1.7 × 1.7) = 22.49 → Normal weight

Benefits of Knowing Your BMI
📈 Health Awareness
Learn whether you fall within a healthy weight range or need to take action.
🧠 Early Warning Sign
A high or low BMI may indicate increased risk for conditions like diabetes, hypertension, or malnutrition.
🎯 Fitness Tracking
Athletes and gym-goers can measure progress as part of body composition monitoring.
🧾 Insurance & Medical Use
Many insurance plans and medical institutions ask for BMI when assessing health coverage or risk.
Limitations of BMI
While BMI is a useful screening tool, it doesn’t measure body fat directly and can be misleading in some cases:
- Muscular individuals may have high BMI but low fat
- Elderly people may have normal BMI but low muscle mass
- Children and teenagers require age/gender-specific percentiles
Use BMI in combination with other metrics like waist circumference or body fat percentage for a complete picture.
