You can't convert kVA (kilovolt.amps) to current (amps) unless you know the source voltage and/or load resistance (ohms) which is drawing the current from the source.

If you know the voltage in kilovolts, you just divide the kilovolt.amps figure by the number of kilovolts and the result is the current in amperes.

If you know both source voltage and load resistance you can use Ohm's Law to get the current:

I = V / R

In words, Ohm's law is:

Current (amps) = Voltage divided by Resistance (ohms)

How do you convert horsepower into amps?

You don't. The units measure different things.


How do you convert micro amps to amps?

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.


Convert 250 kilowatts to amps with 460 volts 3 phase?

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.


What is the formula to convert amperes from 440V to 460V?

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


How do you convert 275 mA to amps?

As a milliampere (milliamp or just mA) is 1/1000th of an ampere, we can convert mA to Amps by just dividing by 1000. Another way is to take the current in mA and move the decimal to the leftthree places to accomplish the division by 1000. Here's the scoop: 275 mA / 1000 = 0.275 Amps Note that the decimal in 275 is to the right of the 5, and it's written as 275.0 (with a 0 added to show where the decimal is). Moving the decimal to the left three places gets up to .275 Amps, but we usually hang a 0 in front of the decimal. To convert Amps to milliAmps, just multiply by 1000 or move the decimal to the right three places. Just the opposite of what we did here to convert the other way.
