DC Amps to Watts Calculation

P(W) => I(A) × V(V)
The P (power) in W (watts) is equal to the I (current) in A (amps), times the V (voltage) in V (volts).

AC single phase amps to watts calculation

P(W) => PF × I(A) × V(V)
The P (power) in W (watts) is equal to the PF (power factor) times the phase I (current) in A (amps), times the RMS V (voltage) in V (volts).

AC three phase amps to watts calculation

Calculation with line to line voltage

P(W) => √3 × PF × I(A) × VL-L(V)
The P (power) in W (watts) is equal to square root of 3 times the PF (power factor) times the phase I (current)in A (amps), times the line to line RMS voltage VL-L in V (volts).

Amps

Amps measure the flow of electricity as an electric current. Specifically, it measures the amount of electrons that flow past a certain point per second.

Volts

Volts are the measurement used to determine how much force is needed to cause the electric current to flow.

Watts

Amps and volts combine to create watts, a measurement of the amount of energy being released. The higher the wattage is, the more power and output from the appliance.

AC and DC power systems

The labels ‘AC’ and ‘DC’ are used to illustrate the types of current flow in a circuit. For direct current (DC) the electric current flows only in one direction. Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current.
