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 Amps to VA Calculation:
The apparent power (S) in volt-amps is equal to Current (I) in amps, times the voltage (V) in volts:
For example, let’s find the volt-amps for a single-phase circuit with 10 amps of current at 220 volts.
S(VA) = I(A) x V(V)
S(VA) = 10 x 220
S(VA) = 2200
Ac Three Phase Amps to VA Calculation :
The apparent power (S) in kilovolt-amps is equal to the square root of 3 current (I) in amps, times the line-to-line voltage VL-L in volts:
For example, let’s find the amps for a 480 volt 3-phase electrical circuit with 80 amps of current.
S(VA) = √3 x 10 x 480
S(VA) = 8313
Where:
-
- S = Apparent Power in Volt-amps (VA)
- I = Current in Amps (A)
- VL-L = Line to Line Voltage in 3-Phase Circuits
- V = Voltage in Volts (v)

Frequently asked questions
A volt-ampere (VA) is a measurement of Real power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits.
Alternating Current) 4000 Volt Amps, is 4000 Watts for a purely resistive load. However, the current flow will be out of phase with respect to the voltage for an inductive (some motors) or capacitive (buried cables) load.
A KVA is simply 1000 volt-amps. A volt is an electrical pressure. An amp is an electrical current. A term called apparent power (VA) is equal to the product of the volts and amps.
Watts = Amps x Volts
20 Amps x 120 Volts = 2400 Watts. 10 Amps x 230 Volts = 2300 Watts.
Now 1HP = 1492W=1.492kW=1.492kVA , assuming power Factor=1.
