How to Convert Amps to kVA

How to convert electric current (amps) to apparent power (kilovolt-amp or kVA).

Amps to kVA conversion

The apparent power S in kilovolt-amps is equal to RMS current I in amps, times the RMS voltage V in volts, divided by 1000:

S = I × V / 1000

So kilovolt amps are equal to amps times volts divided by 1000.

kilovolt-amps = amps × volts / 1000

Or

kVA = A · V / 1000

Amps to kVA example

Question: What is the apparent power in kVA when the current is 12A and the voltage supply is 110V?

Answer:

S = 12A × 110V / 1000 = 1.32kVA
