Unit Explanations
WattW
Source UnitThe watt (symbol: W) is the SI unit of power, defined as the rate of energy transfer equivalent to one joule per second. It measures the amount of energy conversion or transfer that occurs per unit time. In practical terms, it quantifies the rate at which work is done or energy is consumed. The watt is a derived unit in the International System of Units (SI), and it is used extensively in various fields such as electricity, mechanics, and thermodynamics to quantify power output or consumption.
Current Use
The watt is widely used across the globe to measure electrical power, mechanical power, and heat transfer. It serves as a fundamental unit in the fields of electrical engineering, physics, and many applied sciences. It is crucial for calculating energy consumption in households, industries, and for determining the power output of engines and machinery.
Fun Fact
One watt is equivalent to 1/746th of a horsepower.
Joule SecondJs
Target UnitThe joule second (Js) is a derived unit of action, representing the amount of energy in joules multiplied by time in seconds. It is commonly used in quantum mechanics and other fields of physics to describe phenomena such as angular momentum and the Planck constant. This unit emphasizes the relationship between energy and time, particularly in contexts that require quantification of dynamic systems, where energy transfer occurs over time. One joule second corresponds to a change in action of one joule per second.
Current Use
The joule second is primarily used in physics, particularly in quantum mechanics, to express the action of particles and systems. It plays a crucial role in defining the Planck constant, which relates energy to frequency in quantum mechanics. Additionally, this unit finds applications in various scientific fields, including optics and thermodynamics, where the relationship between energy and time is significant. Researchers and scientists utilize the joule second in theoretical calculations and experimental setups.
Fun Fact
The joule second is a key component of the Heisenberg uncertainty principle, which illustrates the trade-off between the precision of a particle's position and momentum.

Definition
The joule second (Js) is a derived unit of action, representing the amount of energy in joules multiplied by time in seconds. It is commonly used in quantum mechanics and other fields of physics to describe phenomena such as angular momentum and the Planck constant. This unit emphasizes the relationship between energy and time, particularly in contexts that require quantification of dynamic systems, where energy transfer occurs over time. One joule second corresponds to a change in action of one joule per second.
History & Origin
The joule second is rooted in the work of James Prescott Joule, who established the principle of conservation of energy in the 19th century. Joule's experiments demonstrated the interconvertibility of mechanical work and thermal energy, leading to the definition of the joule as a unit of energy. The integration of time into this unit resulted in the joule second, capturing the essence of action in physics. This derived unit emerged as critical in quantum mechanics and particle physics, where actions are measured over time.
Etymology: The term 'joule' is named after James Prescott Joule, a British physicist known for his contributions to thermodynamics and energy conservation. The word 'second' derives from the Latin 'secundus', meaning 'following' or 'second in order'.
