A unit of power equal to one thousandth (10-3) of a watt.
It would be 1,000,000th of a watt.
The units mw and mW are the same. They mean milliwatts. The terms Mw and MW, however, means megawats, which is a billion (1x109) times greater than a mw or a mW.Another AnswerThe correct symbol for a watt is an upper-case 'W'. So the correct symbol for a milliwatt is 'mW' (not 'mw'), and the correct symbol for a megawatt is 'MW' (not 'Mw').
The decibel scale is a logarithmic scale where each change in three dB represents a power factor change of two. (3 dB is power times two, 6 dB is power times four, 9 dB is power times 8, etc. Similarly, -3dB is power divided by two, -6 dB is power divided by four, etc.) Zero dB is assigned some arbitrary reference power. One example is 1 mV across 600 ohms. If you double the voltage into a constant resistance, the power quadruples, so 2 mV would be +6 dB, 4 mV would be +12 dB, etc. The letter after dB is the reference power. In the case of dBm, it means that 0 dB is 1 milliwatt, so 2 milliwatt is +3 dB, etc. There are many dB scales, such as dBa, used in sound measurements. Still, fundamentally, 3 dB is a doubling of power, -3 dB is a halving of power, so, for any arbitrary scale, say dBq, then saying +6dBq is saying a power four times higher than 0 dBq. In the end, dBm plus dBm is delta dB, with no scale.
it is the power ratio in decibelsNo, it isn't. dB on its own is a ratio.But when dB has a suffix, the figure is an absolute measurement, not a ratio.For instance, dBm is a measurement of power compared to 1mW.0dBm means zero difference between 1mW and the measured figure. In other words the measured figure is also 1mW.3dBm is 3dB greater than 1mW. -3dB is 3dB less than 1mW. etc.Another suffix is W. 0dBW being 1 watt.There are many more suffixes, some of which are used in only a few specialised cases.
1 mW is one milliwatt.

1 milliwatt of light carries 1 milliwatt of power, and delivers 0.001 joule of energy per second to anything that completely absorbs it. The source of the light doesn't matter.
10 times the base 10 logarithm of some number of milliwatts of power divided by 1 milliwatt of power. Therefore, 0 dbm is the same as 1 milliwatt of power. Often used to describe an amount of audio frequency power.
Any lasers are legal if they are less than one milliwatt. (>1mw)
A decibel is a measure of relative power, to compare one power level with another. 'dBm' means dB relative to 1 milliwatt and is a common unit of power in communications systms, and 0 dBm is the same thing as 1 milliwatt.
A 1 milliwatt lazer beam can go for up to kilometers (12 miles).
7. What is output power?The output power is related to the produced power of the laser beam, which is usually stated in milliwatt (mW). The milliwatt is a unit of power, which is one one-thousand of a watt. Higher power lasers are always more powerful than lower power lasers
I think you mean 1 MW. mw means milliwatt. See link below
You'll need to be more specific as to what you mean by mW. That would technically be milliwatt which is a unit of power and cannot be converted from length.
There are 1000 milliwatts in a watt. There are 1000 watts in a kilowatt. Therefore, there are 1 million milliwatts in one kilowatt.
