I measure the Electromagnetic Field Radiation at a point for example x distance from a source, and i am reading for ex. 15 milli volts per meter. Are these 15 millivolts per meter, equals to 15 milli volts ? I mean, if i do the opposite procedure, and receive a reading of 15 milli volts, at a distance of x units, lets say 3 meters, away from an EMF source, are these 15 milli volts, equals to 15 milli volts per meter ? Are these, two units, related each other and what is their relation ?
