usually above about 1 MHz one does not distinguish between electrical and magnetic fields.
wether only for practical or also for theoretical reasons, i do not know, but that does not matter for us.
i do not think you can convert milliGauss or nanoTesla into dBm, V/m or uW/m^2.
even if you could, you would be comparing apples with oranges to a too large degree.
every frequency and type of wave form has a different impact.
in addition combinations of fields make for a different outcome.
finally health effects are highly personal(  and even changing with time ), not everyone is affected in the same manner.
therefore, although not reliable either, one's own sensitivity is probably usually the best meter.
