WebbThe key point to note from Equation [1] is that skin depth decreases with higher frequency. This means that electric current flows only on the surface of a conductive material at RF frequencies (>10 MHz). For instance, the skin depth of copper at the WIFI or Bluetooth frequency (2.4 GHz = 2.4*10^9) is about 1 micron (1 micrometer = 1/1000 mm). WebbOnce you have determined your body density, you can calculate your percent body fat as follows: % Body Fat = (4.95 / BD − 4.50) × 100 [Siri Equation] Let's look at an example.
