Full Answer

Watts describe the amount of work done over a certain amount of time, or power; 1 watt is 1 joule per second. Foot-candles refer to the amount of light given off from a light source at the distance of 1 foot; a typical tea candle or birthday candle gives off approximately 1 foot-candle at a distance of 1 foot. Because watts and foot-candles describe different things, they can't be equated to one another.

  • Q:

    How many watts make up a kilowatt?

    A:

    According to Convert Units, one kilowatt is made up of 1,000 watts. To convert a certain number of watts into the equivalent amount of kilowatts, one multiplies the number of watts times 0.001. Thus, 600 watts is the same as 0.6 kilowatts, since 600 times 0.001 equals 0.6.
