📐 BMI Formula

BMI = weight (kg) / [height (m)]²

• Height is entered in feet and inches.

• The app converts it to meters using the formula:

  Height (m) = (feet × 0.3048) + (inches × 0.0254)

🟢 Example:

🧪 Sample Input / Output 01: 5 feet 5 inches, 60 kg

• Height in meters = (5 × 0.3048) + (5 × 0.0254) = 1.651 m
• BMI = 60 / (1.651²) ≈ 22.0 → ✅ Normal

---

🧪 Sample Input / Output 02: 5 feet 3 inches, 54 kg

• Height in meters = (5 × 0.3048) + (3 × 0.0254) = 1.6002 m
• BMI = 54 / (1.6002²) ≈ 21.1 → ✅ Normal

💬 BMI Result Categories

• Below 18.5 – Underweight

• 18.5 to 24.9 – Normal

• 25.0 to 29.9 – Overweight

• 30.0 and above – Obese
