1.  电磁场&功率密度dBμV/m to V/m
       V/m = 10  (((dBμV/m) -120) / 20)
V/m to dBμV/m
       dBμV/m = 20 log(V/m) + 120

dBμV/m to dBmW/m2
  dBmW/m2 = dBμV/m – 115.8
dBmW/m2 to dBμV/m
  dBμV/m = dBmW/m2 + 115.8

dBμV/m to dBμA/m
dBμA/m = dBμV/m – 51.5
dBμA/m to dBμV/m
dBμV/m = dBμA + 51.5

dBμA/m to dBpT   
DBpT = dBμA/m + 2

dBpT to dBμA/m
dBμA/m = dBpT – 2
W/m2 to V/m
       V/m = SQRT(W/m2 * 377)
V/m to W/m2
     W/m2 = (V/m)2 / 377

μT to A/m   
A/m = μT / 1.25
A/m to μT   
μT = 1.25 * A/m



2.功率


dBm to Watts
W = 10 ((dBm – 30)/10)

Watts to dBm
dBm = 10log(W) + 30


dBW to Watts
W = 10 (dBW / 10)

Watts to dBW
dBW = 10log(W)



dBW to dBm
dBm = dBW + 30

dBm to dBW
dBW = dBm - 30
