BMI (Body Mass Index) kaise calculate karte hain, formula aur healthy weight range samjhein, free BMI calculator ke saath.

Definition

BMI ek simple index hai jo aapki height ke against weight ko measure karta hai, ye estimate karne ke liye ki weight healthy range mein hai ya nahi. Ye muscle mass jaise factors ko account nahi karta, isliye ek rough screening tool hai, diagnostic nahi.

Formula

BMI = Weight (kg) / (Height (m))²

  • Underweight: BMI < 18.5
  • Normal: BMI 18.5 – 24.9
  • Overweight: BMI 25 – 29.9
  • Obese: BMI ≥ 30

Steps

  1. Apna weight kilograms mein note karein.
  2. Apni height meters mein convert karein (jaise 170 cm = 1.70 m).
  3. Height ko square karein (height × height).
  4. Weight ko height-squared se divide karein — ye aapka BMI hai.
  5. Neeche calculator mein height (cm) aur weight (kg) daal kar instant BMI aur category paayein.

Example

Example: 70 kg weight, 170 cm (1.70 m) height — BMI = 70 / (1.70 × 1.70) = 70 / 2.89 ≈ 24.2, jo "Normal" range mein aata hai.
