Welcome to **amps to watts**, our website about the conversion from the current in amperes to the power in watts. The electric current, denoted I, measured in the unit ampere (A), is the flow of an electric charge. The electric power, denoted P, measured in the unit watt (W), is the work done per unit of time. In the equation P = I × V, V stands for the voltage (electric potential) in volts. Making use of this equation, we are going to transform amperes to watts.

## Convert Amps to Watts

As follows from the equation P_{(W)} = I_{(A)} × V_{(V)}, in order to determine the power P, in addition to I, the voltage V must has to be known. To convert amps to watts, use these formulas:

- DC: P
_{(W)}= I_{(A)}× V_{(V)} - AC, Single Phase: P
_{(W)}= I_{(A)}× PF × V_{(V)} - AC, Three Phase, Line to Line Voltage: P
_{(W)}= I_{(A)}× √3 × PF × V_{L-L(V)} - AC, Three Phase, Line to Neutral Voltage: P
_{(W)}= I_{(A)}× 3 × PF × V_{L-0(V)}

DC, in our context, stands for *direct current*, and, along the same lines, AC means *alternating current*; retail customers usually receive their electric power in the latter form.

In contrast, anything which can run on batteries works on DC, e.g. a laptop. Thus, power supplies also produce an unidirectional flow of electric charge. A power inverter changes DC to AC.

The power factor PF is the fraction of real power drawn in W divided by the supplied power measured in volt-amperes (VA); it’s mathematical definition can be found further below.

Let’s look at how to convert amps to watts by means of an example:

What is the power consumption in W if the current in amperes (often shortened to *amps*) is 2 A and the voltage supply is 220 V, PF=0.6?

- DC: P
_{(W)}= 2 A × 220 V = 440 W - AC, Single Phase: P
_{(W)}= 2 A × 0.6 × 220 V = 264 W - AC, Three Phase, Line to Line Voltage: P
_{(W)}= 2 A × √3 × 0.6 × 220 V = 457.26 W - AC, Three Phase, Line to Neutral Voltage: P
_{(W)}= 2 A × 3 × 0.6 × 220 V = 792 W

When converting amperes to watts, avoid pen and pencil. Also, instead or applying the formula feeding a calculator, we recommended to you utilizing our converter below.

## Amps to Watts Calculator

Employing our amps to watts calculator is easy: Enter the current in amps, then insert the volts. If you have a direct current, then you can already hit the

*convert*button.

Provided that you have an alternating current, then you must also know the number of phases, the power factor PF, and the voltage type in case you have three phases.

Home appliances are plugged into an AC single phase system. Only in cases of AC with three phases the voltage type (line to line RMS or line to neutral RMS voltage) must be specified.

The PF is usually defined as cos (phase angle between voltage and current), and thus takes on a value in the interval [0, 1]. Real power is also called active power and true power.

You have now made it to the concluding paragraph of our amperes to watts article, summarized by this image:

The bottom line of amps to watt is that both, the amps *as well as* the volts, must be known:

In the absence of either, the electric current or the electric potential, the watts cannot be calculated as there is no direct amp to watt relationship.

To locate frequent conversions you can use the search form in the sidebar of our site. There, supposed that x denotes your current, enter, for example, x amps into watts.
