Qu'est-ce que le calculateur d'IMC ?
The BMI Calculator computes your Body Mass Index — a widely used screening tool that estimates body fat based on your height and weight. BMI provides a quick, accessible way to assess whether your weight falls within a healthy range, though it has important limitations. Developed by Belgian mathematician Adolphe Quetelet in the 1830s, BMI is calculated as weight (kg) divided by height squared (m²). The World Health Organization classifies BMI into categories: underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), and obese (30+). This calculator accepts both metric and imperial measurements and provides your BMI with contextual health information. It also explains BMI's limitations and when other health metrics might be more appropriate.

Questions fréquentes
▶Qu'est-ce que l'IMC ?
L'IMC est une mesure de graisse corporelle basée sur la taille et le poids. Il se calcule en divisant le poids (kg) par la taille (m) au carré.
▶Quelle est la plage d'IMC saine ?
Un IMC entre 18,5 et 24,9 est considéré normal. Moins de 18,5 est insuffisance pondérale, 25-29,9 est surpoids et 30+ est obésité.
▶L'IMC est-il précis pour tout le monde ?
L'IMC est utile comme outil de dépistage mais ne tient pas compte de la masse musculaire, la densité osseuse ou la composition corporelle.
▶Is BMI accurate for everyone?
No. BMI doesn't distinguish between muscle and fat mass, so muscular athletes may be classified as overweight despite being healthy. It's also less accurate for elderly people, pregnant women, and growing children. Waist circumference and body fat percentage are often better indicators.
▶What is a healthy BMI range?
The WHO defines 18.5-24.9 as the normal BMI range. However, optimal BMI can vary by ethnicity, age, and individual factors. Some Asian health organizations use lower thresholds (23 for overweight) due to different body composition patterns.
▶Should I rely solely on BMI for health assessment?
No. BMI is a useful screening tool but should be considered alongside other metrics like waist-to-hip ratio, body fat percentage, blood pressure, cholesterol levels, and overall fitness. Consult a healthcare professional for comprehensive health assessment.
