Transformers, alternators, UPS and power supplies are rated in kVA. kVA stands for kilo-Volt-amperes. As the name indicates, it is one kVA is equal to 1000 volt-amperes. Here is an “Amps to kVA converter” that can help you convert amps (amperes) to kVA by simply entering the line voltage and current.

What is ampere?
Ampere is the measure of electric current.
One ampere is equal to the amount of current flow measured by an ammeter when one coulomb of charge is going past it.
What is kVA?
kVA stands for kilo volt-amperes or simply 1000 volt-amperes. It is basically the unit of apparent power and is the product of RMS values of voltage and current.
One kVA is 1000 volt – amperes
Apparent power is the actual amount of power drawn from the source. It includes both true power and reactive power
Calculation of kVA
Single-phase
Single phase apparent power, kVA = (Voltage X Current)/1000
Three-phase when Line to Line voltage is known
For three phase, kVA can be calculated using the following formula if Line to Line voltage is known.
Three phase apparent power, kVA = (√3 X Voltage X Current)/1000 = (1.732 X VoltageLine X Current)/1000
Three-phase when Phase voltage is known
For three phase, kVA can be calculated using the following formula if phase to phase voltage is known
Three phase apparent power, kVA = (3 X VoltagePhase X Current)/1000
