Welcome to **kW to amps**, our page explaining the conversion from the electric power in kilowatts to the electric current measured in amperes. The power *P* is the work conducted over time quantified in the unit watt (W), 1/1000 of a kW. The current *I* is the flow of an electric charge metered in the unit ampere (A). Observe that I = P / V; V denotes the voltage (electric potential) in volts, and read on to learn all about kW to amperes.

## Convert kW to Amps

From the equation in the introduction follows that I_{(A)} = 1000 × P_{(kW)} / V_{(V)}. Thus, in order to measure the current *I* the voltage *V* has to be known in addition to *P*. To change kilowatts to amps, apply the following formulas:

- DC: I
_{(A)}= 1000 × P_{(kW)}/ V_{(V)} - AC, Single Phase: I
_{(A)}= 1000 × P_{(kW)}/ (PF × V_{(V)}) - AC, Three Phase, Line to Line Voltage: I
_{(A)}= 1000 × P_{(kW)}/ (√3 × PF × V_{L-L(V)}) - AC, Three Phase, Line to Neutral Voltage: I
_{(A)}= 1000 × P_{(kW)}/ (3 × PF × V_{L-0(V)})

PF stands for the power factor, defined as the real power drawn in W, divided by the supplied power denoted in volt-amperes (VA). The trigonometric meaning is explained a few lines below.

DC is the abbreviation for *direct current*, and AC is the short form of *alternating current*; retail customers usually receive their electric power in an AC circuit.

In contrast, a computer’s CPU calculates using direct current. In addition, power supplies such as a battery provide an unidirectional flow of electric charge.

As a side note: A device known as inverter converts DC to AC and vice versa.

Let’s have a look on how to convert kilowatts to amps with the help of some examples:

How much is the current in amperes (commonly shortened to *amps*), assumed the power consumption is 1.5 kW and the voltage supply is 110 V, PF=0.6?

- DC: I
_{(A)}= 1000×1.5 kW / 110 V = 13.63 A - AC, Single Phase: I
_{(A)}= 1000×1.5 kW / (0.6×110 V) = 22.72 A - AC, Three Phase, Line to Line Voltage: I
_{(A)}= 1000×1.5 kW / (√3 × 0.6×110 V) = 13.12 A - AC, Three Phase, Line to Neutral Voltage: I
_{(A)}= 1000×1.5 kW / (3 ×0.6× 110 V) = 7.58 A

## About our kW to Amps Calculator

Using our kW to amps calculator at the top of this article is easy: Just enter the power in kilowatts, next insert the voltage. If you have a direct current, then nothing else needs to be done.

If you have an alternating current, additionally select the number of phases and insert the power factor. In case you have an AC system with 3 phases, then the voltage type is required, too.

Only for AC with three phases, a line to neutral coefficient (√3) or a line to line factor, (3), must be accounted for, as can be seen in the formula.

In your house or flat, you most likely have your appliances plugged into an AC *single* phase system. In this case you can forget about the RMS and the other factor.

The power factor PF is usually defined as cosine of the phase angle between voltage and current, so its value lies between 0 and 1. Real power is synonym for active power and true power.

## Kilowatts to Amps

You have reached the concluding part of our kW ampere article, which we wrap up with an image:

The bottom line of kilowatt to amp is that both, the kilowatts *and* the volts, have to be known.

In the absence of the electric power or the electric potential, the electric current in amperes cannot be worked out because of the lack of a direct kW to amp relationship.

Note that you can fill in the search box in the header to locate frequent kilowatt to ampere conversions. Enter, for example, x kW into amps, provided that x denotes your specific power.
