The calculator uses the formula: Energy (kcal) = Body Weight (kg) × Fat Percentage (%) × 9
This formula assumes that each gram of body fat contains approximately 9 kilocalories of energy. This is a standard approximation used in nutrition and fitness calculations.
For example, if you weigh 70 kg and have a body fat percentage of 20%:
Energy = 70 kg × 20% × 9 = 1260 kcal
This means approximately 1260 calories are stored as fat in your body.
