Those two are completely unrelated; it doesn't make sense to convert them.
Two ways to do it. In this particular problem, it's a matter of opinionwhich one is easier and which one is harder.Way #1:Convert dBm to watts, multiply by gains, convert output watts to dBm.+20 dBm = 0.1 watt.Output power = (0.1 watt) x (ap1) x (ap2) x (ap3) = 0.1 x 10 x 4 x 23 = 92 watts = +49.64 dBmWay #2:Convert each gain ratio to dB, then add all dB to input power.ap1 = 10 = 10 dBap2 = 4 = 6.02 dBap3 = 23 = 13.62 dB+20 dBm + 10dB + 6.02 dB + 13.62 dB = +49.64 dBm
90
100 percent is 0 dB.50 percent is - 6 dB.45 percent is -6.935749724 dB.10 percent is - 20 dB.
70 dB is 10 times louder than 60 dB.
How do I convert a .db file?
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.
To convert VA to amps, you can use the formula Amps = VA / Volts. In this case, Amps = 140 VA / 240 V = 0.5833 Amps.
Amps is amps be it DC or AC.
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.
It is impossible to convert dB to dBA. There is only a guess. Scroll down to related links and read "Correlation between sones und phons".
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.
To convert amps to milliamps, multiply by 1000. Therefore, 0.01 amps is equal to 10 milliamps.
Watts are the product of amps x volts.
At what voltage? When you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
