How to Use This Calculator

  1. Enter your body weight in kilograms in the first input field.
  2. Enter your body fat percentage (measured through methods like skinfold calipers, bioimpedance, or DEXA scan).
  3. Click the "Calculate" button to compute the energy stored as fat.

Understanding the Formula

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.

Important Notes

  • This calculator provides an estimate based on the input values. Actual energy values may vary.
  • The accuracy of the result depends on the accuracy of your body weight and fat percentage measurements.
  • For more precise measurements, consider professional methods for determining body fat percentage.
  • This calculator should not replace professional medical advice.

Example Calculation

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.
