À propos de la BMI Calculator - Body Mass Index & Weight Range
Body Mass Index (BMI) is a standardized statistical measure comparing an individual weight to height to categorize body composition into Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (≥30).
Standard BMI Formulas
Metric Formula:
BMI = weight (kg) / [height (m)]²
Imperial Formula:
BMI = [weight (lbs) / [height (in)]²] × 703
Exemples détaillés étape par étape
Metric Calculation (70 kg, 1.75 m)
BMI = 70 / (1.75)² = 70 / 3.0625 = 22.86 (Normal weight)
Imperial Calculation (154 lbs, 5 ft 9 in = 69 in)
BMI = (154 / 69²) × 703 = (154 / 4761) × 703 = 22.74 (Normal weight)
Foire aux questions
What is a healthy BMI for adults?
For most adults, a healthy BMI falls between 18.5 and 24.9. Scores under 18.5 indicate underweight, 25.0 to 29.9 indicate overweight, and 30.0 or higher indicate obesity.
Does BMI apply to athletes and bodybuilders?
BMI does not differentiate between muscle mass and fat mass. Trained athletes with high muscle density may score in the overweight range despite low body fat levels.
