Amps ↔ kVA Calculator



In the world of electricity and power, it’s essential to understand various units and how they relate to one another. One common conversion is from Amperes (Amps) to Kilovolt-amperes (kVA). This article introduces you to an Amps to kVA calculator, explains the formula, provides examples, and answers frequently asked questions to make this conversion process easier.

How to Use

To use the Amps to kVA Calculator, follow these steps:

  1. Input the value of Amperes (Amps) in the ‘Amps’ field.
  2. Input the value of Volts in the ‘Volts’ field.
  3. Click the ‘Calculate’ button.

The calculator will then display the equivalent value in Kilovolt-amperes (kVA).


The formula to convert Amperes (Amps) to Kilovolt-amperes (kVA) is as follows:

kVA = (Amps * Volts) / 1000


  • kVA is the Kilovolt-amperes,
  • Amps is the current in Amperes, and
  • Volts is the voltage in Volts.

This formula takes into account the current and voltage and calculates the apparent power in kVA.


Let’s take an example to illustrate the conversion:

Suppose you have a circuit with a current of 50 Amps and a voltage of 220 Volts. To find the kVA, use the formula:

kVA = (50 * 220) / 1000 = 11 kVA

So, the equivalent power is 11 kVA.

Frequently Asked Questions (FAQs)

Q1: What is the difference between Watts (W) and kVA?

Watts (W) represent real power, while kVA represents apparent power. Real power is the actual power consumed by a device, while apparent power considers the total power, including any power lost due to the phase difference between voltage and current in reactive components like capacitors and inductors.

Q2: Can I use this calculator for three-phase systems?

Yes, the formula and calculator can be used for three-phase systems. Just make sure to input the appropriate current and voltage values for your specific application.

Q3: Why is it important to convert Amps to kVA?

Converting Amps to kVA is essential in electrical engineering and power management to determine the load and capacity of electrical systems accurately. It helps in sizing components, such as transformers, and ensuring the safe and efficient operation of electrical systems.


Converting Amps to kVA is a crucial task in electrical engineering and power management. With the Amps to kVA Calculator and the provided formula, you can easily perform this conversion.
