field strength conversion

(OP)
I would like to convert my field strength readings from V2/M2 to uW /cm2 Can someone please post the conversion equation.
 Thanks

RE: field strength conversion

Assuming that you're in the far field (and in a vacuum or air), then you may assume that the freespace impedance is 377 ohms (120*Pi ohms).  The rest is just Ohm's law and simple math. Pay attention to the units of distance and area.  Bring the units along with the numbers as a sanity check.  It should be volts per meter (linear) and watts per square meter (area) - for example.

PS: Google is your friend.
