Now all of these are rated in amps and mv, my previous question was answered by "you need a 0.001 ohms shunt resistor" so how would I figure out how many mv at amps to sense 20A at 20A? There's no resistors that I can find that have a ex. 75mv at 75 amp ratio :/

It says 50Amp @75mV fsd, that means it's 0.0015 ohms, so if you put 20amp on, it will give 30mV, you can choose one that is 0.001 ohms, or trim the display preset on your meter.
