WebHow to convert dBm to dBW; How to convert dB to dBm; dBm to Watt, mW, dBW conversion table; dBm definition. dBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). The power in decibel-milliwatts (P (dBm)) is equal to 10 times base 10 logarithm of the power in milliwatts (P (mW)): P (dBm) = 10 ⋅ ... Web23 apr. 2015 · So you could say that 0 dBm is is 0 dB greater than 1mW into 600 ohms. (the 600 ohms pins down the voltage). The Simpson meter is doing that. Saying that the measurement is 0 dB relative to the reference level. (they define the 0 dB reference level at the bottom left) Anyway, that's the way I see it. God, I love those old Simpson meters.
