P [mW] = 10^(A/10) = (A/10)th power of ten whare A is power in dBm. 3 dBm = 10^0.3 = approx 2 mW 10 dBm = 1

All dB values are ratios to some specified reference. The dBm means dB with 1 mW as a reference, and dB is 10 times the log of the ratio. Adding dB is li

The power ratio is the square of the voltage ratio, provided the impedance is the same. Just divide the voltages to get a ratio (3.33333
