mW to dBW Conversion
Milliwatt to dBm power converter
Decibel conversion of electric power units. mW to dBm (dB-milliwatt) and/or dBW (dB-Watt). Here is the answer to the question: What is 5.9 mW in dBW or 5.9 mW to Decibel-milliwatts. Use the calculator below to convert any mW values to dBm or dBW.

mW to dBm Conversion
dBm Definition: dBm is the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
The formula bellow can be translated as: "the power P(dBm) in dBm is equal to 10 times the base 10 logarithm of the power P(mW) in milliwatts (mW) divided by 1 milliwatt (mW)":P(dBm) = 10 · log10(P(mW)/1mW)
So, for P = 1 mW is equal to 0 dBm
Convert 100 mW to dBm:
P(dBm) = 10 · log10(100mW / 1mW) = 20 dBm
W to dBW Conversion
The decibel-watt or dBW isthe power ratio in decibels (dB) of the measured power referenced to one Watt (W).:P(dBW) = 10 · log10(P(W)/1W)
Convert 10 W to dBW:
P(dBW) = 10 · log10(10W / 1W) = 10 dBW
