dBm to microvolts into 50 Ω
Type a value in dBm to get it in µV instantly.
2,236,068µV
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 µV
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 = 2,236,070 µV.
