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 Voltage_{Line} 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 Voltage_{Phase} X Current)/1000
