To convert from dB (decibels) to mW (milliwatts), you can use the formula: mW = 10^(dB/10). Simply take the dB value and divide it by 10, then raise 10 to that power to get the mW value. For example, if you have 20 dB, the calculation would be mW = 10^(20/10) = 100 mW.
To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
To convert power in watts to decibels (dB), you can use the formula: dB = 10 * log10(P2/P1), where P1 is the reference power (usually 1 watt) and P2 is the power you are converting (40 watts in this case). Plugging in the values, you would calculate: dB = 10 * log10(40/1) = 16.02 dB.
You cannot directly convert hertz (Hz) to decibels (dB) because they measure different quantities. Hz measures frequency, while dB measures the level or intensity of a sound signal. To get dB from Hz, you would need to measure the intensity or power of the sound and then calculate the corresponding dB value using a reference level.
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
To convert from dB HL (Hearing Level) to dB SPL (Sound Pressure Level), you typically need the specific audiogram for the individual. Once you have the individual's threshold values at different frequencies, you can use them to make the conversion. Each audiometric frequency has a specific conversion factor to convert from dB HL to dB SPL. It is not a direct and consistent conversion across all frequencies.
the first convert the power in dBm to MW, the define of dBm=10 log (P MW) -10 log ( 1mw). example: let P=-2 dBm convert this to dB? answer: Pmw= inv log(-2/10)=0.630mw*1000 micw/mw=630 microw 10log(630)=28dB
How do I convert a .db file?
100 mW to W
dBm us almost exactly the same as dB. The only difference is that there is a reference of 1 Watt = 0 dB, and 1 mW = 0 dBm. 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. PdBm = 10*log10(1000*10W) = 40dBm

4 mW is 24 dB less than 1 watt. (-24 dBW)
Multiply by 1000.
The 'm' in dBm means the power is referenced to 1mW. So, the power in dBm equals 10 times the log of the power in mW, or P(dBm) = 10*log(P(mW)/1mW). For example, 1W = 1000mW, so 10*log(1000/1) = 30dBm.
If I understand the question, it isn't possible to convert dB (a unit of sound energy) to litres (a unit of volume).
To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
One MegaWatt is 1,000,000 Watts and one KiloWatt is 1,000 Watts. To convert MW to KW just multiply by 1,000. Answer is 20,000 KW
