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.
Symbols representing physical quantities, units, mathematical operations and relationships, astronomical bodies, constellations, and the Greek alphabet.
In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
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 .
What is a watt? A watt (symbolized W) is the standard unit of power or radiant flux in the International System of Units (SI). It is derived from the SI base units kilogram (kg), meter (m) and second (s), all of which are constructed from the standard's defining constants.
The watt (symbol: W) is the SI derived unit of power, equal to one joule of energy per second. A human climbing a flight of stairs is doing work at the rate of about 200 watts. An automobile engine produces mechanical energy at a rate of 25,000 watts (approximately 30 horsepower) while cruising.
15 Νοε 2024 · It is defined as being the rate at which 1 1 joule of energy is uniformly transformed in 1 1 second: Hence it can be understood as: the rate at which work is performed when an electric current of 1 1 ampere flows across an electrical potential difference of 1 1 volt. The symbol for the watt is W W. Its LATEX L A T E X code is \mathrm W .
