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 who built the first practical steam engines

A Watt is a unit of power.
In a DC system this is calculated by Amps x Volts.
In an AC system this is calculated by Amps x Volts x Power Factor.

Watt: A standard unit of power defined as one Joule of energy transferred or dissipated in one second.
(Watt) = (Volt) x (Ampere)
(Watt) = 0.746 * (horsepower)

it's the SI unit for power.
Power = force*velocity = current * voltage = energy / time = current^2 * resistance = torque * angular velocity
