Conversion using the Amps to Watts Formula

How to Calculate wattage from amps and volts using DC line current.

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

Watts = Amps × Volts

For Example, DC circuit with a current of 5 Amps and a voltage of 12 Volts, the power is Watts.

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

or, P(W) = 5 amps × 12 volts

or, Real Power = 60 watts

How to Calculate wattage from amps, volts and power factor 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 volt v. Plug these values into the formula:

Watts = pf × Amps × Volts

For Example, If the Voltage consumption is 220V with a phase current of 10A and a power factor of 0.8 the Real Power is watts.

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

or, P(w) = 0.8 × 10 amps × 220 volts

or, Real Power = 1760 watts

How to Calculate wattage from amps, volts and power factor 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 3 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, 3-phase system with 10 Amps of current, 400 Volts line-to-line voltage, and a power factor of 0.8, the power is approximately

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

or, P(W) = 3 × 0.8 × 10 amps × 400 volts

or, Real Power = 5542.4 Watts

How to Calculate wattage from amps, volts and power factor 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 3 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, 3-phase system with 15 Amps of current, 440 Volts line-to-Neutral voltage, and a power factor of 0.8, the power is approximately Watts:

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(line-Neutral)

or, P(W) = 3 × 0.8 × 15 amps × 440 volts

or, Real Power = 18810 watts
