Example calculation

With parameters Age = 3 years, Head: % burned = 100 %, Neck: % burned = 0 %, Anterior trunk: % burned = 50 %, Posterior trunk: % burned = 0 %, Buttocks (both): % burned = 0 %, Genitalia: % burned = 0 %, Upper arms (both): % burned = 0 %, Forearms (both): % burned = 0 %, Hands (both): % burned = 0 %, Thighs (both): % burned = 0 %, Lower legs (both): % burned = 0 %, Feet (both): % burned = 0 % the result is 23.5 % TBSA (Count only partial- and full-thickness burns (exclude erythema)).

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
