3 real worked examples for the IMC calculator. See how we solve common scenarios with full step-by-step math.
1
Adult with normal BMI
Escenario
A 30-year-old woman, 165 cm tall, 60 kg.
Entradas
- Height
- 165 cm (1.65 m)
- Weight
- 60 kg
Pasos del cálculo
- BMI = weight / height²
The standard formula.
- BMI = 60 / (1.65)²
Plug in the values.
- BMI = 60 / 2.7225
Square the height.
- BMI = 22.04
Final result.
Resultado
BMI = 22.04 → Normal weight (18.5–24.9)
2
Overweight adult
Escenario
A 45-year-old man, 178 cm tall, 95 kg.
Entradas
- Height

- BMI = 29.98
Resultado
BMI = 29.98 → Overweight (25–29.9), borderline obese
3
Underweight teen (use percentile for <20)
Escenario
