More information on converting from Amp to Watts:


Definition P.F, Amperes and P (Watts):

Watts: is Working Power (also called Actual Power or Active Power or Real Power). It is the power that actually powers the equipment and performs useful work.

The real power in watts is the power that performs work or generates heat. Power in watts is the rate at which energy is consumed (or generated). One watt is one joule (energy) per second (1 W = 1 J/s).

Resistive devices or loads such as heaters, incandescent lamps are rated in Watts.

Ampere: Amperage is a term often used by electricians, and means electrical current, measured in amperes, or amps. The ampere is the SI unit for electrical current, or the amount of electrical charge that flows through a conductor in a given time. One ampere is a charge of one coulomb — about 6.241 X 1018 electrons — per second flowing past a given point.

P.F: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power.

Power Factor is the cosine of the phase angle between current and voltage.
Power Factor is the ratio of true power to apparent power.
