TYPICAL CONVERSION FORMULAS
Collection of frequently used formulas for RF, Microwaves, Power, Voltage, Current and more
FIELD STRENGTH & POWER DENSITY
V/m = 10 (((dBµV/m) -120) / 20)
dBµV/m to V/m
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

Correction Factors
dBµA/m = dBµV + AF
E-field (take care about
dBµV/m = dBµA/m + 51.5
E-field suppression!)

µA = 10 (dBµA / 20)
dBµA = 20 log(µA)
A = 10 (dBA / 20)
dBA = 20log(A)
dBµA = dBA + 120
dBA = dBµA -120
VOLTAGE
dBµV to Volts
Volts to dBµV
dBV to Volts
Volts to dBV
dBV to dBµV
dBµV to dBV
V = 10 ((dBµV – 120) / 20)
dBµV = 20 log(V) + 120
V = 10 (dBV / 20)
dBV = 20log(V)
dBµV = dBV +120
