This unit is often abbreviated as simply 'Btu,' which is the same abbreviation used for British thermal units, a measurement of heat. British thermal unit per hourĭefinition: The British thermal unit per hour (symbol: Btu/h) is a United States customary system unit of power. The watt as a unit of power should not be confused with its energy counterpart, the watt-hour (and all its multiples/submultiples). The absolute watt was adopted as the SI unit of power in 1960.Ĭurrent 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. 1 absolute watt is equal to 1.00019 international watts. 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. In 1908, the 'international' definitions were defined, with Siemens' definition being adopted as the international watt.

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. History/origin: The watt is named after James Watt, a Scottish inventor. It is defined as 1 joule per second and is used to quantify the rate of energy transfer. work with power's values and properties.Definition: A watt (Symbol: W) is the SI (International System of Units) derived unit of power.

Second: foot-pound-force per second (ft lbf/s) is unit of power.Ībbreviation for foot-pound-force per second is:įt lbf/s Other applications for this power calculator. Converter type: power unitsįirst unit: watt (W) is used for measuring power. Conversion tool with multiple power units. Power units represent power physics, which is the rate at which energy is used-up, either transformed or transferred from its source to elsewhere, by various ways within the nature of physics.
