To convert, please enter the amps and voltage in the boxes below. The calculator can work with three-phase circuits, although the single-phase setting is that which it always used by default.

**The formula for calculating single phase amps to VA is as follows:**

The apparent power, which is measured in volt-amps, is equal to the current, which is measured in amps, multiplied by the voltage, which is measured in volts:

**VA = I X V**

**The formula for calculating three-phase amps to VA is as follows:**

The apparent power, which is measured in kilovolt-amps, is equal to the square root of three times the current, which is measured in amps, multiplied by the line-to-line voltage, which is measured in volts.

**VA = âˆš3 X I X V**
