The watt (symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736–1819). The unit is defined as joule per second and can be used to express the rate of energy conversion or transfer with respect to time. It has dimensions of L2MT−3.
When an object's velocity is held constant at one meter per second against constant opposing force of one newton the rate at which work is done is 1 watt.
In terms of electromagnetism, one watt is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V).
Two additional unit conversions for watt can be found using the above equation and Ohm's Law.
Where ohm () is the SI derived unit of electrical resistance.
Early in the evenin just about supper time,
Over by the courthouse theyre starting to unwind.
Four kids on the corner trying to bring you up.
Willy picks a tune out and he blows it on the harp.
Chorus:
Down on the corner, out in the street,
Willy and the poorboys are playin;
Bring a nickel; tap your feet.
Rooster hits the washboard and people just got to smile,
Blinky, thumps the gut bass and solos for a while.
Poorboy twangs the rhythm out on his kalamazoo.
Willy goes into a dance and doubles on kazoo.

You dont need a penny just to hang around,
But if youve got a nickel, wont you lay your money down?
Over on the corner theres a happy noise.
People come from all around to watch the magic boy.
