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 .
A watt is a unit of power, named after engineer James Watt, which measures the rate of energy transfer. A watt, in electrical terms, is the rate at which electrical work is done when one ampere (A) of current flows through one volt (V).

The meaning of WATT is the absolute meter-kilogram-second unit of power equal to the work done at the rate of one joule per second or to the power produced by a current of one ampere across a potential difference of one volt : 1/746 horsepower. How to use watt in a sentence.
Jun 21, 2024 · Watt, unit of power in the International System of Units (SI) equal to one joule of work performed per second, or to 1746 horsepower. An equivalent is the power dissipated in an electrical conductor carrying one ampere current between points at one volt potential difference. It is named in honour.
Nov 23, 2023 · 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.
What is a watt? A watt (symbolized W) is the standard unit of power or radiant flux in the International System of Units . 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.
Oct 3, 2022 · What Is a Watt? Of all these different units of electricity, wattage is probably the most familiar. For years, you've been buying 40-watt light bulbs and 60-watt light bulbs with the general understanding that a 60-watt bulb is going to be brighter than a 40-watt bulb.
A watt is the SI unit for power. A watt is equal to 1 Joule per second [math]1 \frac{J}{s}[/math] , or [math]1 \frac{kgm^{2}}{s^{3}}[/math] ( energy in an amount of time). [1] A watt of power is about equivalent to a person holding out their arm and moving their fist up and down each second.
