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.

Ecuación de Quetelet del Índice de Masa Corporal

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

Ejemplo Práctico: Adulto de 70 kg y 172 cm (1,72 m) de estatura

Al elevar la estatura al cuadrado (1,72² = 2,9584 m²) y dividir 70 kg entre 2,9584 se obtiene un IMC de 23,7 kg/m² (peso normal según la OMS, cuyo rango saludable para 172 cm es de 54,7 a 73,7 kg).

Preguntas Frecuentes

¿Cuáles son las limitaciones clínicas del IMC?

El IMC es una herramienta de cribado poblacional que no distingue entre masa muscular magra y tejido adiposo; los atletas de fuerza pueden presentar un IMC superior a 25 sin exceso de grasa corporal.
