Example of Body Fat Calculation

Let’s see an example for clarity:

Male Example:

  • Weight: 75 kg
  • Waist: 85 cm
  • Neck: 38 cm

Calculation: Using the US Navy method, the body fat percentage is calculated based on waist and neck measurements. The fat mass is (body fat % / 100) * weight, and lean mass is weight − fat mass.

Result:

  • Body Fat Percentage: 18%
  • Fat Mass: 13.5 kg
  • Lean Mass: 61.5 kg

This allows the individual to monitor fat reduction and muscle gain over time.

Female Example:

  • Weight: 65 kg
  • Waist: 70 cm
  • Hip: 95 cm
  • Neck: 34 cm

Result:

  • Body Fat Percentage: 25%
  • Fat Mass: 16.25 kg
  • Lean Mass: 48.75 kg

Women’s calculations include the hip measurement to improve accuracy.
