Amps to kW Calculator

Use this calculator to convert electrical current in amps to kilowatts (kW). You can calculate DC, AC single-phase, or AC three-phase systems by entering your current and voltage values.

Current Type:

Select the type of electrical current you're using (DC or AC).

Enter Current (Amps):

Enter the current in amps for your system.

Enter Voltage (Volts):

Enter the voltage in volts for your system.

Enter Power Factor (PF):

Power factor is required for AC calculations (default is 1 for DC). Typically between 0.8 and 1.

How the Formula Works

The calculation for converting amps to kilowatts (kW) depends on the type of electrical current:

DC Power: The formula is kW = (Amps × Volts) / 1000.

AC Single-Phase Power: The formula is kW = (Amps × Volts × Power Factor) / 1000.

AC Three-Phase Power: The formula is kW = (√3 × Amps × Volts × Power Factor) / 1000.

Where:

Amps: The electrical current in amperes.

Volts: The electrical voltage in volts.

Power Factor (PF): A decimal value (between 0 and 1) representing the efficiency of the power usage in AC systems.

√3: A constant approximately equal to 1.732, used in three-phase calculations.
