Convert watt to femtojoule/second
watt
Definition: A watt (Symbol: W) is the SI (International System of Units) derived unit of power. It is defined as 1 joule per second and is used to quantify the rate of energy transfer.
History/origin: The watt is named after James Watt, a Scottish inventor. It was first proposed in 1882 by William Siemens who defined it as "the power conveyed by a current of an Ampere through the difference of potential of a Volt." This was the definition used at the time within the existing system of units. In 1908, the "international" definitions were defined, with Siemens' definition being adopted as the international watt. These were used until 1948 when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length. 1 absolute watt is equal to 1.00019 international watts. The absolute watt was adopted as the SI unit of power in 1960.
Current use: As the SI derived unit of power, the watt in all its multiples and submultiples is used in many applications worldwide from radio transmission to use in the electric power industry. The watt as a unit of power should not be confused with its energy counterpart, the watt-hour (and all its multiples/submultiples).
femtojoule/second
Definition: Femtojoule/second is a measure of power, the rate at which work is done or energy is transferred. For conversion purposes, its value is 1.0e-15 times the reference unit, watt.
