Body Fat Percentage:

Definition: Body fat percentage is the proportion of fat in your body compared to your total body weight.

Purpose: It's a more accurate indicator of health and fitness than body weight alone.

The calculator uses the formula:

\[ \text{Body Fat %} = \frac{\text{Fat Mass}}{\text{Total Body Weight}} \times 100 \]

Where:

Fat Mass — The weight of the fat in your body (kg)
Total Body Weight — Your complete body weight including fat, muscle, bones, etc. (kg)

Details: Knowing your body fat percentage helps assess health risks, track fitness progress, and set appropriate weight goals.

Tips: Enter your total body weight and estimated fat mass (from calipers, scans, or other measurement methods).
