Kilowatts to Amps Calculator
Last updated: May 31, 2026
Written by Blake Boege
A kilowatts to amps calculator is a power distribution utility that converts electric power in kilowatts (kW) to active current in amperes (A). Since one kilowatt equals one thousand watts, the tool scales the power value before dividing by voltage and adjusting for power factor and phase multipliers. It is commonly used in industrial energy management, generator sizing, and commercial electrical layouts.
Convert electric power in kilowatts (kW) to current in amperes. Works with DC, single-phase AC, and three-phase AC configuration.
Quick Answer
Convert electric power in kilowatts to current in amperes. Input kilowatts, voltage, and phase configuration to calculate amperage.
Current Type
Formula Used
Amps = (kW × 1000) / Volts = (1.2 × 1000) / 120
Current (Amperage)
10 A
At 120V (DC)
This calculator converts electric power in kilowatts (kW) to electric current in amperes (A). It multiplies kilowatts by 1000 to convert to watts, then applies the voltage division.
How it works
Electric Power Conversion Formulas
To convert kilowatts (kW) to current in amperes (A), use these electrical formulas:
Direct Current (DC)
Amps = (kW × 1000) / Volts
Alternating Current (AC) Single-Phase
Amps = (kW × 1000) / (Power Factor × Volts)
Alternating Current (AC) Three-Phase
Amps = (kW × 1000) / (1.732 × Power Factor × Volts)

Frequently asked questions
Convert kilowatts to watts by multiplying by 1,000, then divide by the voltage. For DC: A = (kW × 1000) / V. For single-phase AC: A = (kW × 1000) / (PF × V). For three-phase AC: A = (kW × 1000) / (1.732 × PF × V).
A kilowatt (kW) is a unit of power equal to 1,000 watts. It is widely used to specify the power output of engines, electric motors, tools, and heaters, as well as billing electricity usage.
At 120V (DC or AC with PF=1.0), 1 kW (1,000 watts) produces: 1000 / 120 ≈ 8.33 amps of current.
Assuming a power factor of 0.85 and a line-to-line voltage of 240V: Amps = (10 × 1000) / (1.732 × 0.85 × 240) = 10000 / 353.3 ≈ 28.3 amps.
