Conversion using the Volts to Watts Formula

How to Calculate Wattage from Volts and Amps using DC line current.

The Real Power p in Watts w is calculated as the voltage v in volts v, times the current I in amps A. Plug these values into the formula:

Watts = Volts × Amps

For Example, let's convert 48 volts to watts for a DC Line circuit with 10 amps of current.

Real Power(P) = Voltage(V) × Current(I)

or, P(W) = 48 volts × 10 Amps

or, Watts = 480W

How to Calculate Wattage from Volts, Amps and Power factor pf using AC Single Phase current.

The Real Power p in Watts w is calculated as the Power factor in pf, times the phase current I in amps A, times the RMS voltage in volts v. Plug these values into the formula:

Watts = pf × Amps × Volts

For Example, let's convert 220 volts to watts for an AC electrical circuit with 30 amps of current and a power factor of 0.9.

Real Power(P) = Power factor(pf) × Current(I) × Voltage(V)

or, P(W) = 0.9 pf × 30 Amps × 220 Volts

or, Watts = 5940W

How to Calculate Wattage from Volts, Amps and power factor pf using AC 3-phase current for Line-to-Line Voltage.

The Real Power p in Watts w is calculated as the square root of 3 times the power factor in pf times the phase current I in amps A, times the line-to-line RMS voltage V_L-L in volts v. Plug these values into the formula:

Watts = 3 × pf × Amps × Volts

For Example, let’s convert 440 Volts to watts for an AC Electrical circuit with 35 amps of current and a power factor of 0.8

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(V)

or, P(W) = 3 × 0.8 pf × 35 Amps × 440 Volts

or, Watts = 21338.86W

How to Calculate Wattage from Volts, Amps and Power factor pf using AC 3-phase current for Line-to-Neutral Voltage.

The Real Power P in watts w is calculated as the 3 times the power factor in pf times the phase current I in amps A, times ths line-to-neutral RMS Voltage _L-N in volts v. Plug these values into the formula:

Watts = 3 × pf × Amps × Volts

For Example, let’s convert 440 Volts to watts for an AC Electrical circuit with 25 amps of current and a power factor of 0.9.

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(V)

or, P(W) = 3 × 0.9 pf × 25 Amps × 440 Volts

or, Watts = 29700W
