## How to Convert Kilowatts to Amps

It is possible to convert kilowatts (kW) to amps using the Watt’s Law power formula. The power formula states that current = power ÷ voltage.

To adapt the power formula to using kilowatts, first start by converting kilowatts to watts, which can be done by multiplying the power in kilowatts by 1,000 to get the number of watts.

Then, apply the power formula by dividing the power (in watts) by the voltage (in volts) to find the current (in amps).

### kW to Amps Formula

Thus, for DC and single-phase AC circuits, the formula to convert kilowatts to amps is:^{[1]}

I_{(A)} = P_{(kW)} × 1,000 / V_{(V)}

The current *I* in amps is equal to the power *P* in kilowatts divided by the voltage *V* in volts.

**For example**, find the current of a circuit with 1 kW of power at 120 volts.

I_{(A)} = 1 kW × 1,000 / 120 V

I_{(A)} = 1,000 W / 120

I_{(A)} = 8.33 A

So, generating 1 kW of power at 120 volts will draw 8.33 amps of current.

### How to Account for Motor Efficiency and Power Factor

Equipment is often not 100% efficient with power usage, and this must be factored in to find the number of amps consumed for a given output power. Efficiency of the motor *η*, is defined as the ratio of power output to power input.

To find the input current required to achieve a certain motor output power, use the following equation.

I_{(A)} = P_{(kW)} × 1,000 / V_{(V)} × η

Thus, the current *I* in amps is equal to the power *P* in kilowatts divided by the voltage *V* in volts times the efficiency *η*.

The magnitude of real and reactive together in alternating current power is called the apparent power, and the power factor is the ratio of real power to apparent power.^{[2]}

To find the input current required to achieve a certain motor output power accounting for power factor and efficiency, use the following equation.^{>[1]}

I_{(A)} = P_{(kW)} × 1,000 / V_{(V)} × η × PF

The current *I* in amps is equal to the power *P* in kilowatts divided by the voltage *V* in volts times the efficiency *η* times the power factor *PF*. Try our power factor calculator to get the power factor if needed.

**For example**, let’s find the current of a 5 kW motor with an efficiency of 75% and power factor of 0.8 at 240 volts.

I_{(A)} = 5 kW × 1,000 / 240 V × 0.75 × 0.8

I_{(A)} = 5,000 W / 144 V

I_{(A)} = 34.72 A

In this example, the 5 kW motor will draw 34.72 amps of current.

### How to Find the Current of a Three-Phase AC Circuit

The formulas to convert kilowatts to amps for a three-phase AC circuit are a little different from the formula for a single-phase circuit. Use one of the formulas below for line to line or line to neutral RMS voltages.^{>[1]}^{[3]}

### Using Line to Line Voltage

I_{(A)} = P_{(kW)} × 1,000 / V_{L-L(V)} × η × PF × √3

This formula measures the current draw for one pair of wires in the three-phase system; to calculate the current for all three pairs of wires, you need to multiply the result by three.

### Using Line to Neutral Voltage

I_{(A)} = P_{(kW)} × 1,000 / V_{L-N(V)} × η × PF × 3

This formula measures the current draw for all three wires in the three-phase system; to calculate the current for a single wire, you need to divide the result by three.

**For example**, find the current usage of a 25 kW three-phase motor with an efficiency of 80% and a power factor of 1 at 240 volts (line to line).

I_{(A)} = 25 kW × 1,000 / 240 V × 0.8 × 1 × √3

I_{(A)} = 25,000 W / 332.55 V

I_{(A)} = 75.18 A

To convert watts to amps, use our watts to amps conversion calculator.
