EMC Conversion Calculator

RF unit converter.

Type into any value box. Every other unit updates automatically from that entry. Voltage, current and power are RMS equivalents for the selected purely resistive impedance.

System impedance, ohms

Change impedance and all impedance-based current and power values recalculate.

From dBµV

Let Z = impedance in ohms and U = µV.

dBmV = dBµV - 60
dBV = dBµV - 120
dBµA = dBµV - 20 log10(Z)
dBmA = dBµV - 20 log10(Z) - 60
dBA = dBµV - 20 log10(Z) - 120
dBpW = dBµV - 10 log10(Z)
dBm = dBµV - 10 log10(Z) - 90
dBW = dBµV - 10 log10(Z) - 120
µV = 10^(dBµV / 20)
mV = 10^((dBµV - 60) / 20)
V = 10^((dBµV - 120) / 20)
µA = 10^((dBµV - 20 log10(Z)) / 20)
mA = 10^((dBµV - 20 log10(Z) - 60) / 20)
A = 10^((dBµV - 20 log10(Z) - 120) / 20)
pW = U² / Z
mW = (U² / Z) × 10^-9
W = (U² / Z) × 10^-12

To dBµV

dBµV = dBmV + 60
dBµV = dBV + 120
dBµV = dBµA + 20 log10(Z)
dBµV = dBmA + 20 log10(Z) + 60
dBµV = dBA + 20 log10(Z) + 120
dBµV = dBpW + 10 log10(Z)
dBµV = dBm + 10 log10(Z) + 90
dBµV = dBW + 10 log10(Z) + 120
dBµV = 20 log10(µV)
dBµV = 20 log10(mV) + 60
dBµV = 20 log10(V) + 120
dBµV = 20 log10(µA) + 20 log10(Z)
dBµV = 20 log10(mA) + 20 log10(Z) + 60
dBµV = 20 log10(A) + 20 log10(Z) + 120
dBµV = 10 log10(pW) + 10 log10(Z)
dBµV = 10 log10(mW) + 10 log10(Z) + 90
dBµV = 10 log10(W) + 10 log10(Z) + 120
