How many mW equals a decibel?" The power reference 0 dB is equivalent to 0.001 watts or 1 mW, when we use dBm. That is power matching. Zin = Zout. http://engr.nmsu.edu/~etti/fall96/communications/db/db.html http://en.wikipedia.org/wiki/DBm In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one which maximizes transfer of a voltage signal to the load. http://en.wikipedia.org/wiki/Impedance_bridging
That must be really nonsense.
1 megawatt = 1 000 kilowatts
100mw
my guess? about 10,000 mw.....
MW stands for Megawatt.
4 mW is 24 dB less than 1 watt. (-24 dBW)
1000
1 watt/second equal to 1 Joule
You didn't clarify into what units you want to convert.The prefix "M", or "mega", means millions. So, MW is millions of watts.Watt is a power unit. One watt is equal to one joule/second.
dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt. dBm is different from dB. dBm represents absolute power, whereas in audio engineering the decibel is usually a voltage ratio of two values and is used then to represent gain or attenuation of an audio amplifier, or an audio damping pad.

1 kw = 0.001 mw 25 kw = 0.025 mw

true
The Welsh word for 'decibel' is desibel.
dBm means "decibels relative to 1 mW". B is the symbol for the unit bel, and decibel is 1/10th of a bel. Bels are used to measure ratios between two measurements, not an absolute measurement by themselves. In this case you're measuring relative to 1 mW. So, for instance, if a device is producing 100 mW, this will be 100 times your reference of 1 mW. "100 times" the power is equal to 20 decibels, so this would be 20 dBm.
