My system is 220 volt. I have an output of 160 Amp. How much is that in Kw?

Watts = Volts X Amps, so 220V at 160A = 35200 Watts, or 35.2 kW. That's a lot of power.

Ampere measures how much current is going. Think of it as the weight of water flowing in from of you every second, to make an analogy. Kw is a measure of power. It is the product of the flow times the energy (or the speed). In electricity, this requires to know the voltage.
If your power system is 110 volt, then 160 Amp would be 17600 w (or 17.6 kW or 17.6 kVA).

I don't know what Kva is. But you can't convert 160 amps to Kw. Amps are a unit of current and Watts are a unit of power.

In literal terms, the ratio of power (Watts=joules/sec) and current (Amperes=coulomb/sec) is voltage( joules/coulomb).
Since you are apparently talking about alternating current (AC), though, we are dealing with vector quantities and the relationship is a bit more complicated...
The short answer is that it depends on the nature of impedance of the load.
A load with large reactive component has a lower power factor. The power is the RMS current times the RMS voltage times the power factor. (Ref. 1)
If the load "looks" a lot like a resistor, the power factor is very nearly unity- but if it has net inductance or capacitance, there is a reactive component which reduces the "active" power. (Ref. 2)
Note that "Apparent" power is measured in volt-amperes (VA), "Active" power is measured in Watts, and "Reactive" power is measured in reactive volt-amps (VAR).
