Webster Dictionary

  1. Watt(noun)

    a unit of power or activity equal to 107 C.G.S. units of power, or to work done at the rate of one joule a second. An English horse power is approximately equal to 746 watts

  2. Origin: [From the distinguished mechanician and scientist, James Watt.]


  1. Watt

    The watt is a derived unit of power in the International System of Units, named after the Scottish engineer James Watt. The unit, defined as one joule per second, measures the rate of energy conversion or transfer.

Chambers 20th Century Dictionary

  1. Watt

    wot, n. the practical unit of electrical activity or power—from James Watt (1736-1819).

The Standard Electrical Dictionary

  1. Watt

    (a) The practical unit of electric activity, rate of work, or rate of energy. It is the rate of energy or of work represented by a current of one ampere urged by one volt electro-motive force; the volt-ampere. It is the analogue in electricity of the horse power in mechanics; approximately, 746 watts represent one electric horse power. Ohm's law, taken as C = E, gives as values for current, C and E, and for electro- motive force C R. In these formulas, C represents current strength, R represents resistance and E represents electro-motive force. Then a watt being the product of electro-motive force by current strength, we get the following values for rate of electric energy, of which the watt is the practical unit: (1) E2 -- (2) C*E -- (3) C2 * R. The equivalents of the watt vary a little according to different authorities. Ayrton gives the following equivalents: 44.25 foot pounds per minute--.7375 foot pounds per second--1/746 horse power. These values are practically accurate. Hospitalier gives .7377 foot pounds per second. Hering gives .737324 foot pounds per second, and 1000/745941 horse power. It is equal to 1E7 ergs per second. Synonym--Volt-ampere. (c) It has been proposed to use the term as the unit of energy, instead of activity or rate of energy (Sir C. W. Siemens, British Association, 1882); this use has not been adopted and may be regarded as abandoned. [Transcriber's note; Watt is a unit of POWER--energy per unit of time.]

Sample Sentences & Example Usage

  1. Vikrant Parsai:

    You don’t have to be the brightest bulb in the house; when the darkness comes, you will be 100 watt.

  2. Jamal Hameedi:

    [ The Ranger Raptor ] really is the best handling pickup truck I’ve driven and not by an insignificant margin, the watt’s link and everything, I think it would go pretty well in America.

  3. Frederic Grappe:

    This figure means little because we don't know whether it's the power he produced for 20 or 40 minutes. And you usually lose one Watt per minute after 20 minutes, if your power meter is well calibrated, you have landmarks.

  4. Aldous Huxley:

    To us, the moment 8:17 A.M. means something - something very important, if it happens to be the starting time of our daily train. To our ancestors, such an odd eccentric instant was without significance - did not even exist. In inventing the locomotive, Watt and Stevenson were part inventors of time.

  5. Anis Aouini:

    This project that is planned for India consisting of 50 Saphonians producing 20 kilowatts of power, a total of one mega watt, will be a wind farm. This power produced in south India, could meet the demands of a small village of 1000 houses even if the energy will be directly injected to the general Indian electricity network. But it's an approximation to ease the understanding for viewers: it's about 1000 houses in India.
