Note, For higher values like 5×10^{3}, 10×10^{6}, 1.6 x10^{12}, enter the value like this for scientific notation as 5e3, 10e6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase Kva to Amps Calculation:
The current I in amps is equal to 1000 times the apparent power (S) in kilovoltamps, divided by the voltage V in volts:
For example, let’s find the current for a 220volt circuit with 30 kVA of apparent power.
I_{(A)} = 1000 x 30 ÷ 220
I_{(A)} = 136.364 A
Ac Three Phase Kva to Amps Calculation :
Calculation with Line to Line Voltage:
The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovoltamps, divided by the square root of 3 times the linetoline RMS voltage V_{LL} in volts:
For example, let’s find the current for a 440volt 3phase circuit with 40 kVA of apparent power.
I_{(A)} = 1000 x 40 ÷ √3 x 440
I_{(A)} = 52.486 A
Calculation with Line to Neutral Voltage:
The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovoltamps, divided by 3 times the line to neutral RMS voltage V_{LN} in volts:
I_{(A)} = 1000 x I_{(KVA)}÷ 3 x V_{(LN)}
I_{(A)} = 1000 x 25 ÷ 3 x 440
I_{(A)} =18.93 A
Where:

 I = Apparent Power in Kilovoltamps (Kva)
 V = Voltage in volts
 I = Current in amperes
 Cosθ = Power factor in AC circuits
 V_{LL} = Line to Line Voltage in 3Phase Circuits
 V_{LN} = Line to Neutral Voltage in 3Phase Circuits

Frequently asked questions
5 kVA is equivalent to 5000volt amps.
The formula for converting kVA into kW is:
For example, a 200kVA generator with a power factor of 0.8 outputs 80kW actual power; 200 kVA x 0.8 = 160 kW.
Your Authorised Service Capacity (measured in kVA) is the level of 'apparent power' reserved from the network to guarantee the provision of a certain volume of power.
A voltampere (VA) is the voltage times the current flow feeding an electrical load. A kilovoltampere (kVA) is 1000 voltamperes. Electrical Real power is measured in watts (W)
A body is said to have 1 watt of power if it can perform 1 joule of work in 1 second. Power is defined as the rate at which work is performed, or energy is converted.
