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.
Femtojoule SecondfJ·s
Target UnitA femtojoule second (fJ·s) is a derived unit of action or angular momentum in the International System of Units (SI), representing the amount of action produced when one femtojoule of energy is applied over one second. It is equal to 10^-15 joules multiplied by seconds. The femtojoule is a sub-multiple of the joule, where 1 femtojoule equals 10^-15 joules, making it suitable for measuring very small quantities of energy in high-energy physics and quantum mechanics contexts.
Current Use
Femtojoule seconds are predominantly used in high-energy physics, quantum optics, and nanotechnology. Researchers utilize this unit to measure the very small energy scales involved in quantum state transitions and to analyze the dynamics of atomic and subatomic particles. It is essential in experiments that deal with laser interactions and in the study of molecular interactions.
Fun Fact
The femtojoule second is used to quantify actions in quantum mechanics, where tiny energy scales are the norm.

Femtojoule Second
power • Non-SI
Definition
A femtojoule second (fJ·s) is a derived unit of action or angular momentum in the International System of Units (SI), representing the amount of action produced when one femtojoule of energy is applied over one second. It is equal to 10^-15 joules multiplied by seconds. The femtojoule is a sub-multiple of the joule, where 1 femtojoule equals 10^-15 joules, making it suitable for measuring very small quantities of energy in high-energy physics and quantum mechanics contexts.
History & Origin
The concept of femtojoules emerged in the late 20th century as scientists began working with increasingly smaller scales of energy, particularly in fields like particle physics and quantum mechanics. The term 'femto-' is a metric prefix indicating a factor of 10^-15, derived from the Danish word 'femten' meaning 'fifteen'. As the need for precise measurements at the femtometer scale arose, the femtojoule became essential for quantifying energies involved in atomic and subatomic processes.
Etymology: The prefix 'femto-' originates from the Danish word 'femten', meaning fifteen, indicating the scale of 10^-15. The term 'joule' is named after the English physicist James Prescott Joule, who established the principle of conservation of energy.
