Watt vs what

  •  
  • Watt and what are two words that are very close in pronunciation and spelling, but have different meanings and are often confused. We will examine the definitions of watt and what, where these words came from and some examples of their use in sentences.

    A watt is a unit of measure of power, equal to one joule per second. A watt is a measurement of electricity and the rate at which it dissipates or is used. The word watt was derived from James Watt, a Scottish scientist and inventor who is famous for his work on steam engines, among other things. The plural form of watt is watts.
