Enter the total current (amps) and the total voltage (volts) into the Calculator. The calculator will evaluate the kVA from Amps. This calculator can also evaluate the amps or volts when given the other variables.

kVA from Amps Formula

The following two example problems outline the steps and information needed to calculate the kVA from Amps.

kVA = I * V / 1000


  • kVA is the kVA from Amps ((kilo-volt-amps))
  • I is the total current (amps) 
  • V is the total voltage (volts) 

To calculate kVA from Amps, multiply the amperage by the voltage, then divide the result by 1000.

How to Calculate kVA from Amps?

The following steps outline how to calculate the kVA from Amps.

  1. First, determine the total current (amps). 
  2. Next, determine the total voltage (volts). 
  3. Next, gather the formula from above = kVA = I * V / 1000.
  4. Finally, calculate the kVA from Amps.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total current (amps) = 30

total voltage (volts) = 20

kVA = I * V / 1000 = ?
