Is mw and mW the same in watts . is it the same or is mW stronger voltage then mw?

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').


Prove dbm plus dbm equals db?

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.


What is the dbm?

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.

How many watts of power are represented by 0 dbm?

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.

How do I convert Watt seconds to milliwatts seconds?

To convert Watt seconds to milliwatt seconds, you can multiply the value in Watt seconds by 1000. This is because 1 Watt is equal to 1000 milliwatts. So, 1 Watt second is equal to 1000 milliwatt seconds.


What is the formula to convert dbm to db?

To convert dBm (decibels relative to 1 milliwatt) to dB (decibels), you can use the formula: ( \text{dB} = \text{dBm} - 30 ). This is because 0 dBm corresponds to 1 milliwatt, and dB represents a ratio relative to 1 watt. Therefore, subtracting 30 adjusts the dBm value to reflect a comparison to 1 watt instead of 1 milliwatt.


What is d b m?

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.
