converting dBm to uV/m

It is a little like asking how to convert giraffes to file cabinets. THere
is no conversion factor from dBm to microvolts/meter. One is a power. One
is a field strength.

Hey all,

I'm still skeptical about this formula:

Field Strength (uV/m) = 10 ^ ( (107 - |dBm| ) / 20 )

Is this valid? I saw this formula somewhere and jotted it down.
