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.
Nanojoule SecondnJ·s
Target UnitThe nanojoule second (nJ·s) is a derived unit that represents energy in joules multiplied by time in seconds. Specifically, one nanojoule is equal to 10^-9 joules, and thus a nanojoule second quantifies a very small amount of energy acting over a small duration of time. In the context of power, it can be used to express energy transfer or work done in micro-scale applications, such as in the fields of nanotechnology and precision instrumentation.
Current Use
The nanojoule second is primarily used in fields that require precise measurements of energy transfer over time, particularly in nanotechnology, quantum mechanics, and electronics. For example, it is relevant in studying the energy levels of electrons in quantum dots or semiconductor devices, where energy changes occur at the nano-scale. In research and development, the application of this unit helps in analyzing energy efficiency in microelectronics and other advanced materials.
Fun Fact
The nanojoule second can quantify energy changes that occur in picoseconds or faster, relevant in high-speed electronics.

Nanojoule Second
power • Non-SI
Definition
The nanojoule second (nJ·s) is a derived unit that represents energy in joules multiplied by time in seconds. Specifically, one nanojoule is equal to 10^-9 joules, and thus a nanojoule second quantifies a very small amount of energy acting over a small duration of time. In the context of power, it can be used to express energy transfer or work done in micro-scale applications, such as in the fields of nanotechnology and precision instrumentation.
History & Origin
The concept of energy as a product of work and time dates back to classical mechanics with the formulation of energy units in the 19th century. The joule, named after James Prescott Joule, was defined in 1843 as the energy transferred when a force of one newton moves an object one meter. The prefix 'nano-', derived from the Greek word 'nanos' meaning 'dwarf', was adopted to denote one billionth (10^-9) of a unit, formalized in the metric system in the late 20th century.
Etymology: The term 'nano' comes from the Greek word 'nanos' meaning 'dwarf', indicating a factor of 10^-9, while 'joule' is named after the English physicist James Prescott Joule.
