Watt - Wikipedia
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer.

Writing with SI (Metric System) Units - NIST
2010年1月13日 · When the unit is derived from the name of a person, the symbol or the first letter of the symbol is an uppercase letter (W for the unit "watt" or Pa for the unit "pascal"). Prefixes: Symbols of SI prefixes that mean a million or more are capitalized and those less than a million are lower case (M for mega (millions), m for milli (thousandths)).
watt - Metric System
The watt, symbol W, is the SI coherent derived unit of power, or rate of energy transfer. It is the special name for the kilogram metre squared per second cubed, symbol kg m 2 s -3 . One watt is equal to the transfer of one joule in one second .
Watt - Simple English Wikipedia, the free encyclopedia
The watt (symbol: W) is the SI unit of power. It is named in honour of the physicist James Watt (1736–1819). The watt is a method of measuring the rate of energy transfer of an appliance. A one watt lightbulb, for example, will change one joule of electrical energy into light energy (and some heat/sound) every second, thus "consuming" it.
Watt (W) electrical unit - RapidTables.com
Watt is the unit of power (symbol: W). The watt unit is named after James Watt, the inventor of the steam engine. One watt is defined as the energy consumption rate of one joule per second. One watt is also defined as the current flow of one ampere with voltage of one volt. Convert watt to milliwatt, kilowatt, megawatt, gigawatt, dBm, dBW.
What is Watt? - Energy Theory
2023年11月23日 · Watt is the SI unit of power and is defined as the rate of energy transfer per unit of time. Combining all other base units of SI such as kilogram (kg), meter (m), and second (s), constructs the standard defining constants. After the name of a Scottish inventor and engineer named James Watt (1736-1819), the term watt was coined.
