Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 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 kilovolt-amps, divided by the voltage V in volts:
For example, let’s find the current for a 220-volt 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 kilovolt-amps, divided by the square root of 3 times the line-to-line RMS voltage VL-L in volts:
For example, let’s find the current for a 440-volt 3-phase 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 kilovolt-amps, divided by 3 times the line to neutral RMS voltage VL-N in volts:
I(A) = 1000 x I(KVA)÷ 3 x V(L-N)
I(A) = 1000 x 25 ÷ 3 x 440
I(A) =18.93 A
Where:
-
- I = Apparent Power in Kilo-volt-amps (Kva)
- V = Voltage in volts
- I = Current in amperes
- Cosθ = Power factor in AC circuits
- VL-L = Line to Line Voltage in 3-Phase Circuits
- VL-N = Line to Neutral Voltage in 3-Phase Circuits

Frequently asked questions
5 kVA is equivalent to 5000-volt 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 volt-ampere (VA) is the voltage times the current flow feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. 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.
