What is an Amps to kVA Calculator?

An amp to kVA calculator is a very useful tool in making rapid calculations for the conversion of ampere – electrical current to kilovolt-ampere – apparent power, or kVA. It helps workers engaged in electrical systems, especially those using single-phase and three-phase power configurations.

You can also Calculate Amps to kVA manually by using the following formula.

Formula for Single-Phase System

To calculate kVA from current (I) and voltage (V) in a single-phase system:

    kVA = (I × V) / 1000

Where:

I = Current in amps
V = Voltage in volts
kVA = Apparent power in kilovolt-amperes

Example Calculation for Single-Phase

If the current is 10 amps and the voltage is 240 volts:

    kVA = (10 × 240) / 1000 = 2.4 kVA

Formula for Three-Phase System

To calculate kVA in a three-phase system:

    kVA = (I × V × √3) / 1000

Where:

I = Current in amps
V = Voltage in volts
√3 = Square root of 3, approximately 1.732
kVA = Apparent power in kilovolt-amperes

Example Calculation for Three-Phase

If the current is 10 amps and the voltage is 240 volts:

    kVA = (10 × 240 × √3) / 1000 ≈ 4.15 kVA

Why Use an Amps to kVA Calculator?

Using an Amps to kVA calculator provides:

Fast Calculations: Instant results without the need for manual math.
Accurate Load Planning: Helps identify the kVA requirements for different devices, ensuring circuits can handle the load.
Safety and Efficiency: Prevents overloading, reducing the risk of electrical faults or system downtime.

What is Amps and kVA

Amps (Amperes) measure the amount of electric current flowing through a conductor.
kVA (Kilovolt-Amperes) measures the apparent power in an electrical circuit, combining both real power (in kW) and reactive power (in kVAR).

How to use Amps to kVA calculator?

Enter the current in amps.
Choose whether you’re calculating for Single-Phase or Three-Phase.
For Single-Phase, input the voltage in volts.
For Three-Phase, input the voltage and calculate using the √3 factor.
Click “Calculate” to get the kVA result.
