Amps (A)
Amps is the flow of electricity as an electrical current.
Specifically, it measures the number of electrons that flow past a certain point per second, so basically one Ampere is defined as the current that flows with electric charge of one Coulomb per second.

Kilovolt-amp (kVA)
The unit KVA (kilovolt amperes) is the power associated with the electric current.
1 kilo-volt-ampere is equal to 1000 volt-ampere. kVA is equal to the square root of 3 (1.732) times amps times volts, divided by 1,000.

Volt amp rating is just the Kilowatt rating determined at unity power factor. (V.A = watts / power factor).

Why kVA?
By the rating of any device, we come to know exactly how much energy will it be able to supply to the load connected to it.
For example, Transformers have copper losses and iron losses.
Copper loss depends on current and iron loss depends on voltage. Neither depend on power factor. A kVA rating is helpful in determining this loss.

Single phase: It comes to the home with two wires: active and neutral. The neutral wire is connected to the earth (water pipe, earth stake, etc.) at the switchboard.

Three phase: It has four wires, three actives (called phases) and one neutral. The neutral wire is earthed at the switchboard.

Amps to kVA calculator
It is an online calculator which converts Amp and voltage to kilovolts – amp. It is a simple operating tool and requires you to enter the appropriate units in the given text fields. The calculate tab carries out the calculation once the values are entered correctly.
The first step is to select the phases it can either be single phase or three phases. Then you have to enter the current and the voltage in the respective fields. A single click will execute the calculation and the final answer would be in kVA. Clicking on the reset tab will erase all the previous entries in order to perform new calculations.

The mathematical formulas to convert Amps to kVA are as follow:

Single phase amps to kVA calculation formula

S(kVA) = I(A) × V(V) / 1000
The apparent S in kilovolt-amps is equal to I in amps, times the V in volts, divided by 1000.

3 phase amps to kVA calculation formula

Calculation with line to line voltage

S(kVA) = √3 × I(A) × VL-L(V) / 1000
The apparent S (power) in kilovolt-amps is equal to phase I (current) in amps, times the line to line RMS voltage VL-L in volts, divided by 1000.

Calculation with line to neutral voltage

S(kVA) = 3 × I(A) × VL-N(V) /1000
The apparent S in kilovolt-amps is equal to phase I in amps, times the line to neutral RMS voltage VL-N in volts, divided by 1000.
