dBm to W/mW Converter Calculator
Conversion of electric power units. Decibel-W to W / mW. Here is the answer to the question: What is 0 Decibel-W in Watt or 0 Decibel-W to Watts. Use the calculator below to convert any Decibel-W values to Watts or miliwatts.
dBm to mW or W Converter
dBm to miliwatt (mW) / Watt (W), Conversion Table (*)
(*) Some values are rounded
The power conversion from dBm to mW or Watt is given by the formula:
P(dBm) = 10(P(mW)/10)
Convert 20 dBm to milliwatts:
P(mW) = 10(20/10) = 100 mW
So, the power of 20 dBm is equal to 100 mW or 0.1 W (Watt).
Convert -30 dBm to milliwatts:
P(mW) = 10(-30/10) = 0.001 mW
So, the power of -30 dBm is equal to 0.001 mW or 0.000001 W = 1 μW.
