BMI is a general screening tool — it doesn’t directly measure body fat.

Explanation

Body Mass Index (BMI) is a weight-to-height screening metric.

BMI = weight(kg) ÷ height(m)^2
Category bands follow the common WHO-style cutoffs (Underweight / Normal / Overweight / Obesity).
Healthy weight range is computed from BMI 18.5–24.9 for your height.

Note: BMI does not directly measure body fat (muscular people can score “high”).
