🧠 What Is Body BMI?
BMI (Body Mass Index) is a widely used measure to classify body weight relative to height. It provides a simple numeric value that places your body in a health category:
- Underweight
- Normal weight
- Overweight
- Obese
It’s not perfect—it doesn’t account for muscle—but it’s an effective first step in identifying health risks related to weight.
🧮 Example Calculation
Let’s say you weigh 70 kg and your height is 170 cm.
- Convert height to meters: 170 cm = 1.70 m
- Apply the BMI formula:
BMI = 70 / (1.70 × 1.70) = 24.22
Results:
- Body BMI: 24.22
- Category: Normal Weight
- Ideal Range: 53.5 – 72.0 kg
You’re in the healthy range!
📊 BMI Categories Explained
| BMI Value | Body Category |

| 18.5 – 24.9 | Normal Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 – 34.9 | Moderately Obese |
| 35.0 – 39.9 | Severely Obese |

🎯 Ideal Weight Range
Ideal weight is based on the healthy BMI range of 18.5 to 24.9. The calculator automatically computes this for your height.
For Example:
- If you’re 170 cm tall
- Your ideal weight range is 53.5 – 72.0 kg
This range is your health target zone.
