Convert from var to watt

Unit Definition (var)
The varis a unit of the reactive electric power delivered by an alternating current (AC) circuit. In an AC circuit, the electric potential or voltage (measured in volts) and the current (in amperes) alternate direction, varying smoothly according to sine curves. In a purely resistive circuit, current is in phase with voltage. In a purely inductive circuit, the variations of the current would lag the variations in the voltage by 1/4 cycle, or 90°. In real circuits, the current can be separated into two parts: a part in phase with the voltage, and the "reactive" part, which lags the voltage by 90°. The reactive part does no net work; it simply heats the conductor. Reactive current does perform important magnetizing and voltage-regulation functions in real circuits. The reactive power is the product of the voltage and the reactive part of the current. The name of the unit is an acronym for volt-ampere-reactive.

Unit Definition (watt)
The watt is the SI unit of power. Power is the rate at which work is done, or (equivalently) the rate at which energy is expended. One watt is equal to a power rate of one joule of work per second of time. This unit is used both in mechanics and in electricity, so it links the mechanical and electrical units to one another. In mechanical terms, one watt equals about 0.001 341 02 horsepower (hp) or 0.737 562 foot-pound per second (lbf/s). In electrical terms, one watt is the power produced by a current of one ampere flowing through an electric potential of one volt. The name of the unit honors James Watt (1736-1819), the British engineer whose improvements to the steam engine are often credited with igniting the Industrial Revolution.
