There is no formula for converting watts to foot-candles because the two measure different things. Watts are a unit of measurement for power while foot-candles are units of measurement for the amount of light something generates.
Know MoreWatts 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.
Learn more about MeasurementsJoules are a measurement of work, while watts are a measurement of power; because they measure different things, they cannot be converted directly. However, they can be used to describe one another; joules can be converted to watt times seconds, and watts can be converted to joules per second.
Full Answer >In general, watts are calculated by taking the current, in amps, and multiplying by the voltage. AC currents involve additional steps, which may include multiplying by a power factor (for single-phase currents) or multiplying by a power factor and a coefficient (for three-phase currents).
Full Answer >Watts are a unit of power, whereas a BTU is a measurement of energy. A single BTU per hour corresponds to approximately 0.293 watts of power.
Full Answer >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.
