Welcome to **4 volts to watts**, our post about the 4 volt to watt conversion.

Here we show you how to convert four volts to watts using the formulas for DC as well as AC circuits.

If you have been wondering *how many watts is 4 volts*, or if you have been looking for 4v in watts, then you are definitively right here.

We not only explain you the conversion of 4 volts to watts, but also feature a voltage to watt calculator you will like.

## How many Watts is 4 Volts

The answer to the question *how many watts is 4 volts* depends on the flow of electric charge, either one-directional in direct current (DC), or bidirectional in case of alternating current (AC).

In case of 4 volts in an AC circuit, the power factor PF and number of phases make a difference, in addition to the connection scheme of the wires in case of 3-phase AC.

See the 4 volts to watts formulas in the next section, and make sure to check out our converter which you can find after the voltage to wattage example calculations.

## 4 Volts to Watts Conversion

To convert 4 volts to watts, determine your electric current in amperes (A), then apply the formula below which corresponds to your circuit:

**W = [A] × [4 V]**

AC, 1 Phase:

**W = PF × [A] × [4 V]**

AC, 3 Phase, Line to Line (L-L):

**W = √3 × PF × [A] × [4 V]**

AC, 3 Phase, Line to Neutral (L-N):

**W = 3 × PF × [A] × [4 V]**

To learn what the power factor, line to line and line to neutral voltage in the context of changing 4 volts to watts stand for, read our article volts to watts, located in the header menu.

For the example 4 volts to watts conversions below, we assume a power factor of 0.5 and an electric current of 1.5 amperes. Therefore, for 4v to watts we get:

- Direct current (DC): W = [1.5 A] × [4 V] = 6 watts
- Alternating current (AC), 1 Phase: W = 0.5 × [1.5 A] × [4 V] = 3 watts
- Alternating current (AC), 3 Phases, L-L: W = √3 × 0.5 × [1.5 A] × [4 V] = 5.2 W
- Alternating current (AC), 3 Phases, L-N: W = 3 × 0.5 × [1.5 A] × [4 V] = 9 watts

Remember, these values for 4 volts in watts are example calculations under the assumption PF = 0.5 and I = 1.5 A. For *your* power factor, amperage and circuit, use our calculator.

Enter 4 in the *Volts* field, then choose your circuit from the drop-down menu. If requested, insert the PF. Next, in the *Amps* field, enter your electric current, then hit *Convert*.

If you wish to start 4 volts to watts over, first hit *Reset*, then proceed as explained above.
