Graph 2 • 2D Height vs. Weight BMI Contour Map Plots your exact (Height, Weight) coordinate against BMI 18.5, 25, and 30 contours
BMI 18.5 BMI 25.0 BMI 30.0 You: 172 cm, 70.0 kg (23.7) Standing Height (145 cm → 200 cm) vs. Body Weight (40 kg → 130 kg)
Graph 3 • Healthy Weight Benchmarks for 172 cm Height Compares your weight against WHO and Asia-Pacific normal ceilings
Your Current Weight 70.0 kg (BMI 23.7) Minimum Healthy Weight (BMI 18.5) 54.7 kg Midpoint Ideal Weight (BMI 21.7) 64.2 kg Asia-Pacific Normal Ceiling (BMI 22.9) 67.7 kg WHO Global Normal Ceiling (BMI 24.9) 73.7 kg
Summary: BMI of 23.7 kg/m² lies in the Normal weight (18.5–24.9) zone on the WHO 12 to 40 kg/m² reference scale.
Summary: At 70 kg and 172 cm, your BMI is 23.7 kg/m², which falls in the WHO "Normal weight (18.5–24.9)" range (and "Overweight / At-Risk (23.0–24.9)" under Asia-Pacific/Indian clinical consensus guidelines). For your height, a WHO BMI between 18.5 and 24.9 corresponds to 54.7–73.7 kg.

Équation de Quetelet de l’Indice de Masse Corporelle

BMImetric = Weight (kg)[Height (m)]2,   BMIUS = 703 × Weight (lb)[Height (in)]2
BMI = weight (kg) / [ height (m) ]²; Imperial: BMI = 703 × weight (lb) / [ height (in) ]²

Exemple : Adulte de 70 kg mesurant 172 cm (1,72 m)

En divisant 70 kg par 1,72² (2,9584 m²), on obtient un IMC de 23,7 kg/m² (corpulence normale selon l’OMS, plage de poids santé de 54,7 à 73,7 kg).

Quelles sont les limites de l’IMC ?

L’IMC est un indice de dépistage qui ne distingue pas la masse musculaire de la masse grasse ; il doit être complété par le tour de taille et le bilan clinique.
