Understanding body mass index
BMI relates body weight to height and gives a rough indication of weight. The calculator shows the value, the WHO classification and the recommended normal weight range for your height.
- Formula: BMI = weight (kg) ÷ height² (m). Example: 75 kg at 1.78 m gives about 23.7.
- Categories (WHO): under 18.5 underweight, 18.5–25 normal, 25–30 overweight, over 30 obese.
- Limits: Athletes with lots of muscle can have a high BMI without being overweight.
