Volts to VA – Conversion, Formula, example and table

With this calculator you can convert volts to VA easily, just by entering some basic parameters in the online calculation tool.

To facilitate the understanding of the conversion, some examples of Volt a VA are shown , the formula that must be used, how to perform the conversion in 1 step and a table with the most common equivalences.

Formula of conversion of Volts to VA:

voltios to va

  • AC = Amps.
  • LL = Line-Line Voltage.
  • LN = Line-Neutral Voltage.
  • VA (1Ø) = Kilovoltio-Amperes monofasico.
  • VA (2Ø) = Kilovoltio-biphasic amp.
  • VA (3Ø) = Kilovoltio-Ampere trifasico.

How to convert from Volts to VA in 1 step

Step 1:

Only the variables between them should be multiplied depending on the type of load (single-phase, two-phase or three-phase). For example: A three-phase pumping equipment has a current of 3.3 Amp and 220 Volts, to find the power, the formula for three-phase equipment should be used as follows: √3 × 3.3Ax220V, resulting in = 1257VA.


Examples of volt to VA conversions:

Example 1:

A monophasic gym treadmill consumes 18.5Amp and has a voltage of 110Volt, how many VA will the equipment have ?.

Answer: // It’s easy you just have to multiply the variables between them, the amps by the volts, in the following way: 18.5Ampx110V = 2035VA.

Example 2:

A three-phase isolation transformer has an amperage of 48.2 Amp and a voltage of 460 Volts, how many VA will the transformer have ?.

Answer: // To find the result you must multiply the variables in the following way 48.2Ampx460Voltx√3, the result will be: 38403VA.

Example 3:

A biphasic UPS has an amperage of 24.5Amp and a voltage of 120Volt, how many VA will this UPS have ?.

Answer: // The formula must be used for two-phase loads as follows: 24.5x120x2 = 5880VA.

Note: If you could notice it is very important to differentiate between line-line voltage and line-neutral voltage otherwise the results may be erroneous, so we suggest verifying the requested in the table before entering the values, it can also be useful Conversion calculator of Volts Linea-Linea a Linea -neutro and vice versa.

Note: Previous conversions are made from a 10 Amp amperage and three phase AC power. For different variables you should use the online calculator that appears at the beginning.

How to use the Volts to VA calculator:

The first thing is to choose the number of phases, then you must enter the data shown on the left side of the table, it is important to check what is requested in the table (voltage type, VL-L or VL-N) due to that of this voltage will depend the correct result of the calculation, then you must enter the amperage and finally click on calculate.
