Example Calculation

To understand how the calculator works, consider the following example:

  • Weight: 70 kg
  • Height: 175 cm
  • Age: 30 years
  • Gender: Male

Step 1: Calculate BMI:
BMI = Weight / (Height in meters)^2
= 70 / (1.75 × 1.75)
= 22.86

Step 2: Calculate Body Fat Percentage (U.S. Navy Formula Approximation):
For males: Body Fat % = (1.20 × BMI) + (0.23 × Age) − 16.2
= (1.20 × 22.86) + (0.23 × 30) − 16.2
= 27.43 − 16.2 + 6.9
≈ 18.13%

The calculator will display BMI: 22.86 and Body Fat: 18.13%, indicating a healthy body composition.
