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.
Microjoule SecondμJ·s
Target UnitThe microjoule second (μJ·s) is a derived unit in the field of power, representing the product of energy in microjoules (μJ) and time in seconds (s). It is used to express the amount of energy delivered or consumed over a specific time period, with one microjoule equivalent to one millionth of a joule. Thus, the microjoule second provides a measure of energy transfer rate over time intervals, essential for various scientific and engineering applications, particularly in fields requiring precise energy measurements.
Current Use
The microjoule second is widely used in research and development environments where precise energy measurements are required, particularly in fields such as photonics, semiconductor physics, and materials science. Its ability to quantify energy transfer over time makes it invaluable in experiments involving lasers, batteries, and other energy systems. Instruments measuring power output and energy consumption often utilize this unit for better granularity in data collection.
Fun Fact
A microjoule is one-millionth of a joule, illustrating the precision of energy measurements in microscopic applications.

Microjoule Second
power • Non-SI
Definition
The microjoule second (μJ·s) is a derived unit in the field of power, representing the product of energy in microjoules (μJ) and time in seconds (s). It is used to express the amount of energy delivered or consumed over a specific time period, with one microjoule equivalent to one millionth of a joule. Thus, the microjoule second provides a measure of energy transfer rate over time intervals, essential for various scientific and engineering applications, particularly in fields requiring precise energy measurements.
History & Origin
The concept of energy measurement dates back to the early 19th century with the formulation of the work-energy principle. The joule, named after James Prescott Joule, became a standard unit of energy in the International System of Units (SI). The microjoule was derived as a sub-multiple to facilitate measurements at smaller scales, particularly in physics and engineering contexts. The combination of microjoules and seconds into the microjoule second reflects the growing need to quantify energy transfer over time in various scientific experiments and applications.
Etymology: The term 'micro' comes from the Greek word 'mikros,' meaning small, while 'joule' is named after the English physicist James Prescott Joule.
