🧠 What is BMI?
BMI (Body Mass Index) is a number derived from your weight and height. It is a widely used indicator for:
- Classifying weight status
- Identifying potential health risks
- Setting weight goals
It’s not a perfect measure (as it doesn’t account for muscle mass), but it’s a valuable screening tool.
🔢 Example Calculation
Let’s say someone is 78 kg and 172 cm tall.
- Convert height to meters: 172 cm = 1.72 m
- BMI = 78 / (1.72 × 1.72) = 26.37
Result:
- BMI: 26.37
- Category: Overweight
- Status: Above Healthy Range
This indicates the user should consider weight management to reduce long-term health risks.
