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.
dB or dBW relativ to 1W : dBm for dB relativ to 1 milliwatt. 0 dBm= 1 mW = -30dBW . Its interesting,but these terms are used interchangeably at times, erroneously.The term dBm is used by communications engineers and it is absolute.Most Power meters commercially available have this scale. It is : dBm=10log(base 10)(P1/P2) at two different Power points.Power is read always across a 50 Ohm resistor.IEEE has made this a standard and 1mW=0dBm(-40dBm is 100nW accross 50 Ohm and +20dBm is 100mW). As far as I know dB(not DB)refers simly to gain(and loss/attenuation as -dB).It is different this time as the equation is not Power but a simple ratio: dB=20log(base 10)(Gain or attenuation).One can have a reference and above that reference he is talking in positive dBs(Gain) and below in negative dBs(loss or attenuation).Such scales can then be modified as we have done for Acoustic Emission where we talk in dBae and our refence is the "perfect" sensor giving us ONLY 1microVolt(!) Peak output noise.Anyway a good goal.So for 40dBae a sensor/Amplifier(40dB Gain)output across a 50 Ohm resistor is 10mV.
See link below (output is in MW electrical). Multiply by three for thermal output
MW stands for milliwatts and refers to the power output of the laser pointer. It indicates the strength of the laser beam emitted by the pointer.
MW stands for megawatt and is a unit used to measure the power output of wind energy systems. It represents the amount of electricity that a wind turbine can generate at a given moment.
mW stands for milliwatt, which is a unit of power equal to one-thousandth of a watt. In the context of lasers, mW is often used to specify the output power of the laser, indicating how much energy the laser is emitting per unit time.

"MW" on a laser typically refers to the laser's power output, measured in milliwatts. It indicates the strength or intensity of the laser beam. The higher the MW, the more powerful the laser and potentially the greater the risk of harm it can cause.
You mean MW (megawatts) not mw (milliwatts). If it is generating 200 MW, that is 200,000,000 watts, at 25,000 volts, the current is given by watts/volts = 8000 amps.
As of 2007, worldwide there were 439 operational nuclear reactors with total capacity of 372,002 MW; making the average output 846 MW. However, the average new reactor can be expected to be larger. The reactors so far built in the US range up to about 1100 MWe electrical output, but new ones up to about 1500 MWe are planned
MWe and MWt are units for measuring the output of a power plant. MWe means megawatts of electrical output, and MWt means megawatts of thermal output. For example, a nuclear power plant might use a fission reactor to generate heat (thermal output) which creates steam to drive a turbine to generate electricity (electrical output). A reactor that generates 200 MWt (50 MWe), and another reactor that generates 800 MWt (200 MWe).
The Vermont Yankee plant is currently licensed to produce 620 MW. It was originally licensed to produce 520 MW, but received an uprate in power output in May of 2006.
The power output of a nuclear power plant can vary, but on average, a typical nuclear power plant produces around 1,000 megawatts (MW) of electricity. This can vary depending on the size and design of the plant.
