What do these numbers mean?

Electricity consists of electric and magnetic fields.  The electric fields are measured in volts per meter (V/m) and the magnetic fields are measured in milliguass (mG).

Radio frequency radiation also consists of electric and magnetic fields, however other than in the near field exposure (typically a few inches or feet at most) the fields are coupled together.  A formula for power density has been adopted for this far field exposure.  Green Evolution generally uses the power density measurement of microwatts per centimeter squared (uW/cm2).

Please read PowerWatchUKs page on conversions of measurements for more on this -

To convert W/m2 to mW/cm2 divide by 10.
To convert W/m2 to mW/m2 multiply by 1,000.
To convert µW/m2 to W/m2 divide by 1,000,000 (1 million).
