Amps to Kilowatts Calculator

Use our Amps to Kilowatts Calculator to easily convert electrical current (Amps) into power (Kilowatts). Whether you are working with DC, single-phase AC, or three-phase AC, this tool simplifies the conversion for your specific needs.

How to Use the Calculator

1. Select the Current Type:

   • Choose the type of current from the drop-down menu: either DC, AC Single-phase, or AC Three-phase.

2. Input the Current:

   • Enter the current value in Amps, and choose the appropriate unit (mA, A, kA).

3. For AC Circuits:

   • If you select an AC current type (single or three-phase), you'll be prompted to choose the voltage type (line-to-line or line-to-neutral) and input the voltage value in the appropriate units (mV, V, or kV).
   • For AC circuits, the power factor field will also be displayed. It defaults to 1 but can be adjusted depending on your system's efficiency.

4. Calculate:

   • After entering all the required data, click the "Calculate" button to get the result.
5.

Output Results

The tool provides the following power output results:

• Power in Kilowatts (kW): The main result you're looking for.
• Power in Watts (W): If you prefer to see the result in watts.
• Power in Milliwatts (mW): For smaller-scale applications.

Understanding the Inputs and Outputs

• Current (Amps): The amount of electrical current flowing through the circuit. Common units are Amps (A), milliamps (mA), or kiloamps (kA).

• Voltage (Volts): The potential difference across the circuit, with unit options including millivolts (mV), volts (V), or kilovolts (kV). For AC circuits, you’ll also specify whether the voltage is measured line-to-line or line-to-neutral.

• Power Factor: Only required for AC circuits, this value (ranging from 0 to 1) represents the efficiency of the power being used. A power factor of 1 means maximum efficiency.

  Power (Kilowatts, Watts, Milliwatts): The calculated output power based on the current, voltage, and power factor inputs.

Formula for Conversion

• For DC Circuits:

  $$P(kW) = \dfrac{V \times I}{1000}$$
  

  Where:

  • $V$ is the voltage (in volts)
  • $I$ is the current (in amps)

• For Single-Phase AC Circuits:

  $$P(kW) = \dfrac{V \times I \times PF}{1000}$$

  Where:

  • $V$ is the voltage (in volts)
  • $I$ is the current (in amps)
  • $PF$ is the power factor

• For Three-Phase AC Circuits:

  $$P(kW) = \dfrac{\sqrt{3} \times V \times I \times PF}{1000}$$

  This accounts for the power distributed across three conductors in a three-phase system.

Why Use this Calculator?

This tool is useful for:

• Electrical Circuit Design: Ensure correct sizing for components such as wires and breakers.
• Power Management: Accurately calculate power consumption for energy efficiency.
• Generator Sizing: Determine the power requirements to prevent overloading or underutilization of your system.
