## How to Convert Volt-amperes to Amps

Before we can convert volt-amps to amps we need to understand a little bit more about what these measurements are. A *volt-ampere* (VA) is a measure of the apparent electrical power while an *amp* (A) is a measure of electrical current.

Thus, to convert between them we need to use the formula for power.

Power = Voltage × Current

Using the power formula as the starting point, by reversing the formula you can convert power in volt-amps to current in amps:

Current_{(A)} = Power_{(VA)} ÷ Voltage_{(V)}

So, using the formula above, converting volt-amps to amps is as easy as dividing the volt-amps by the voltage.

**For example,** let’s find the amps for a single-phase electrical circuit with 1,800 volt-amps of power at 120 volts.

Current_{(A)} = 1,800 VA ÷ 120 V

Current_{(A)} = 15 A

So, a circuit with 1,800 volt-amps of apparent power at 120 volts has a current rating of 15 amps.

### How to Convert Volt-amps to Amps for Three-Phase Circuits

The volt-amps to amps conversion is a little bit different for a three-phase electrical circuit. To calculate, use the modified three-phase formula.

Current_{(A)} = Power_{(VA)} ÷ (√3 × Voltage_{(V)})

For a three-phase electrical circuit, the current in amps is equal to the power in volt-amps divided by the square root of three times the voltage.

In this formula, voltage is the line-to-line voltage of the circuit.

**For example,** let’s find the amps for a three-phase electrical circuit with 33,255 volt-amps of power at 480 volts.

Current_{(A)} = 33,255 VA ÷ (√3 × 480 V)

Current_{(A)} = 33,255 VA ÷ 831.38 V

Current_{(A)} = 40 A

We can see that a circuit with 33,255 VA of apparent power at 480 V will have a current rating of 40 A.
