BMI Calculator

Computes your body mass index from height and weight (metric or imperial), the WHO classification it falls into, and the weight range that would count as healthy for your height.

Notes

  • BMI = weight / height² (kg/m²). It ignores body composition: muscular people can read as overweight and people with little muscle as normal.
  • The WHO bands apply to adults; children and teens use age-specific percentile charts instead.
  • This is an educational estimate, not medical advice; consult a professional for decisions about your health.
