You don't. They measure quite different things, so there is no standard conversion. Ampere is a unit of electrical current. Decibel (dB) is a measure of signal gain.

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
To convert amps to kilowatts (kW), you can use the formula: kW = (Amps × Volts) / 1000. For example, if you're using a standard voltage of 240 volts, then 150 amps would equal 36 kW (150 × 240 / 1000 = 36). If the voltage is different, just adjust the calculation accordingly.
