Answer:
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.

You can't convert kVA (kilovolt.amps) to amps unless you know either the source voltage (as was explained above here in the first answer) or the load resistance which is drawing the current from the source.
If you know them both you can use Ohm's Law to get the amperage:
I = V / R
In words, Ohm's law is:
Current (amps) equals voltage divided by resistance (ohms)
