How do you calculate your BMI?
The BMI (Body Mass Index) is your weight (kg) divided by the square of your height (m): BMI = weight ÷ height². Example: 70 kg for 1.75 m → 70 ÷ (1.75 × 1.75) ≈ 22.9.
How to read the result?
- Under 18.5: underweight
- 18.5 to 24.9: normal weight
- 25 to 29.9: overweight
- 30 and above: obesity
⚠️ BMI is a general indicator that does not account for muscle mass or body shape. It is not a substitute for professional medical advice.
Frequently asked questions
Is BMI reliable for athletes?
Not always: a very muscular athlete can have a high BMI without excess fat, because muscle weighs more than fat.
Is my data stored?
No, the calculation is entirely local and nothing is sent to the Internet.
