With this calculator you can convert in a single step from Volts to Watts automatically, easily, quickly and for free.
We also explained that the formula should be used to convert from volts to watts, how convert from volts to watts in 1 single step, some illustrated examples of volts to watts and a table with the main conversions from volts to watts.
Most common power factor values in different constructions, appliances and motors.
Formula to convert, pass, calculate and transform from volts to watts, single-phase, two-phase and three-phase:
- W DC = Watts DC (direct current).
- W 1Ø = Watts 1 phase.
- W 2Ø = Watts 2 phases.
- W 3Ø = Watts 3 phases.
- V L-N = Volts line-neutral.
- V L-L = Volts line-line.
- I AC1Ø = Current / monophase Amps.
- I AC2Ø = Current / Biphasic Amps.
- I AC3Ø = Current / Three- phase Amps.
- FP = Power factor.
How to convert from volts to watts in 1 single step:
You only have to multiply the variables shown in the formula, according to the type of DC or AC current and the number of phases. Byexample: A biphasic coffee machine has a voltage of 240V (AC, LN), a power factor of 0.81 and a current of 5.4Amp, how many watts does the coffee machine have? To know the answer you just have to take the formula to find biphasic watts by multiplying the variables in the following way: 2x240x5,4 × 0.81 = 2099.52Watts (Formula: V (LN) xIxF.Px2 = watts).
Examples of conversions from volts to Watts:
A single-phase vacuum has an AC voltage of 127 volts (LN), 4.3 Amps and a power factor of 0.92, how many watts does the vacuum have?
Rta: // The first thing to do is identify the formula to be used, because the equipment is single-phase and AC (alternating current), you should use the formula: V (LN) xIxF.P, replacing the variables would be: 127Vx4.3 × 0.92 = 502.41Watts.
A biphasic hair dryer has an AC voltage of 220V (LL), an amperage of 8Amperes and a power factor of 0.96, which will be the power in watts of the hair dryer ?.
Rta: // Take the formula for two-phase equipment (Formula: 2xV (LN) xIxF.P = watts), because we have the LL voltage, we must pass it to LN, in the following way: multiply 220V (LL) / √3 = 127V (LN), this is the way in which the voltage from Linea-Linea to Linea-Neutro is converted, then we simply multiply the variables that appear in the formula: 2x127x8x0,96 = 1950Watts.
The lighting of an industry has a three-phase voltage of 480Volts (LL), a power factor of 0.87 and an amperage of 200Amp, how many Watts does the lighting have ?.
Rta: // As it is a three-phase illuminaicon, the formula must be taken: (√3xV (LL) xIxF.P = watts), then replacing the variables I get: √3x480x200x0,87 = 144,660Watts.

How to use the calculator from Volts to Watts:
Initially you must choose the type of current you want AC or DC and the number of phases in case of choosing AC, then you must enter the data shown on the left side of the tool, it is important to review what is requested in the table due to the fact that according to what is required, line-line or neutral-line voltage must be input, then you must enter the power factor and finally the amperage.
