dBm to dBµV
Type a value in dBm to get it in dBµV instantly.
127dBµV
That's about the same as a Wi-Fi router. That is about 100 milliwatts.
What it means
How strong is that signal?
Voltage figures assume the 50 ohm system impedance of radio equipment. In a 75 ohm cable television system the same power gives a different voltage.
The math
How to convert dBm to dBµV
dBm is an absolute level against one milliwatt: mW = 10^(dBm ÷ 10), and dBm = 10 × log₁₀(mW). Add 30 for dBW, and in 50 ohms add 107 for dBµV.
Example: 20 dBm = 127 dBµV.

The units
About these units
dBm (dBm)
Decibels relative to one milliwatt, the standard radio power level.
dBµV (dBµV)
Decibels relative to one microvolt. In 50 ohms it is dBm plus 107.
