To convert microamps to amps, you need to divide the value in microamps by 1,000,000. This is because one microamp is equal to one millionth of an amp. So, if you have a current of 500 μA (microamps), you would divide 500 by 1,000,000 to get 0.0005 amps.

You don't. The units measure different things.
You have to know the power loading and phase angle (or power factor) between each pairh of the phases, otherwise you could be making serious errors.
For the same power - Watts - you need to run twice as many amps at 220V than at 440V. For the same load, it'll pull half the amps at 220V than it did on 440V
Start by using Ohm's law. 10 volts and 200 microamps requires 50,000 ohms. From that, subtract the impedance of the meter. Place the final resistor in series with the meter. Add a resistor in series of such a size that when there is 10v it will allow 200 u amps to flow.
Ohms is a unit of resistance. Amps is a measure of current. They are related by Ohm's Law where Voltage = Current x Resistance. In your example Resistance = 100 x 10 to the 6th power So V in Micro volts over 100 would yield current expressed as micro amps. So if you had 100 volts you would have 1 micro amp.
A current of 287 microamps, which is 0.000287 amps.
4.3 amps
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.

Watts are the product of amps x volts.
To convert amps to milliamps, multiply by 1000. Therefore, 0.01 amps is equal to 10 milliamps.
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.
To convert high voltage (HV) amps to low voltage (LV) amps, you can use the formula: HV amps = LV amps x (LV voltage / HV voltage). By rearranging the formula, you can calculate LV amps by dividing HV amps by the ratio of HV voltage to LV voltage.
Amps and volts are two separate parts of power measurement and do not convert into each other. Multiplying amps times volts will give you the measurement of wattage.
