BMI Kya Hai?
BMI ka full form Body Mass Index hai. Ye ek number hai jo aap ke weight aur height se calculate hota hai. Adults mein BMI broad weight categories samajhne ke liye use hota hai. Ye simple aur quick measure hai, lekin direct body-fat percentage nahi batata aur muscle aur fat mein farq nahi karta.
CDC BMI ko screening measure ke taur par describe karta hai aur individual health ko samajhne ke liye doosri information bhi consider karne ki salah deta hai. CDC Adult BMI guidance.
BMI Calculate Karne Ka Formula
Metric BMI Formula
BMI = Weight (kg) ÷ [Height (m)]2
Agar height centimeters mein hai to pehle meters mein convert karein. 175 cm = 1.75 m.
Centimeters ke liye direct formula bhi use ho sakta hai: BMI = [Weight (kg) ÷ Height (cm)2] × 10,000.
Imperial BMI Formula
BMI = [Weight (lb) ÷ Height (in)2] × 703
Agar height feet aur inches mein ho to total inches nikaalein. 5 ft 6 in = 66 inches.
CDC BMI calculation guidance mein official formulas dekhe ja sakte hain.
BMI Manually Step by Step Kaise Nikalein?
- Apna weight measure karein.
- Apni height measure karein.
- Correct units select karein.
- Height ko square karein.
- Weight ko squared height se divide karein.
- Pounds aur inches mein ×703 karein.
- Age ke mutabiq result interpret karein.
Metric BMI Example
Agar adult ka weight 70 kg aur height 1.75 m ho:
70 ÷ (1.75 × 1.75) = 22.9
20+ adult ke liye 22.9 standard healthy-weight category mein aata hai.
Imperial BMI Example
Agar weight 160 lb aur height 5 ft 6 in ho:
5 ft 6 in = 66 inches
(160 × 703) ÷ (66 × 66) ≈ 25.8
20+ adult ke liye 25.8 standard overweight category mein aata hai.
Adults Ka BMI Chart
| BMI Range | Category |
|---|---|
| 18.5 se kam | Underweight |
| 18.5 se below 25 | Healthy Weight |
| 25 se below 30 | Overweight |
| 30 ya zyada | Obesity |
Ye fixed ranges 20+ adults ke liye hain. Official source ke liye CDC Adult BMI Categories dekhein.
Bachon Aur Teenagers Ka BMI Kaise Samjhein?
2–19 saal mein body grow kar rahi hoti hai, is liye adult 18.5, 25 aur 30 wali fixed ranges use nahi karni chahiye. BMI ko age aur sex-specific BMI-for-age percentiles ke saath interpret kiya jata hai.
- 5th percentile se kam: Underweight
- 5th se below 85th: Healthy Weight
- 85th se below 95th: Overweight
- 95th percentile ya zyada: Obesity
Official percentile result ke liye CDC Child and Teen BMI Calculator use karein.
Height Aur Weight Se BMI Kaise Nikalein?
Agar aap ke paas height aur weight hai to BMI nikalna possible hai. Sabse important baat units ka sahi hona hai. Metric mein kg + meters aur U.S. customary mein pounds + inches use karein.
Misal: 180 cm ko 1.80 m mein convert karein. 5 ft 10 in ko 70 inches banayein.
Calculator Par BMI Kaise Nikalein?
Basic calculator se bhi BMI nikal sakte hain. Height ko square karein, weight ko squared height se divide karein, aur pounds/inches mein ×703 use karein. Automatic calculation ke liye SmartWebHub BMI Calculator use karein.
Centimeters Se BMI Kaise Calculate Karein?
BMI = [weight (kg) ÷ height (cm)2] × 10,000
Example: 70 kg aur 175 cm se BMI approximately 22.9 aata hai.
Feet Aur Inches Se BMI Kaise Calculate Karein?
Feet ko 12 se multiply karein aur remaining inches add karein. 5 ft 6 in = 66 inches. Phir pounds aur inches ka standard formula use karein.
Height Ko Square Kyun Karte Hain?
BMI formula mein height squared hoti hai. Is ka matlab hai height ko usi height se multiply karna. 1.75² = 1.75 × 1.75 = 3.0625.
BMI Calculate Karne Ki Common Mistakes
- 175 cm ko 175 m samajhna.
- Height ko square na karna.
- Kg ko inches ke saath mix karna.
- Pounds/inches mein 703 factor bhoolna.
- Bachon par adult BMI chart apply karna.
Kya BMI Muscle Ko Measure Karta Hai?
Nahi. BMI height aur weight par based hota hai. Highly muscular athletes ka BMI high aa sakta hai chahe body fat us number ke mutabiq high na ho.
BMI Men Aur Women Ke Liye Different Hai?
