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.
Pound-Foot-Secondlbf·ft·s
Target UnitThe pound-foot-second (lbf·ft·s) is a unit of power in the imperial system, defined as the rate at which work is done when one pound of force is applied over a distance of one foot in one second. This unit is often used in engineering and physics to describe mechanical power, particularly in the context of engines and machinery. The pound-foot-second reflects the relationship between force, distance, and time, and serves as a practical measure for various applications, especially in the United States.
Current Use
Today, the pound-foot-second is primarily used in the United States and certain engineering fields to quantify power in machinery, engines, and structural applications. It is often referenced in specifications for motors and generators, where it provides a relatable measure for power output and efficiency. Its continued relevance in engineering education and practice ensures that it remains a vital part of the power measurement landscape.
Fun Fact
The pound-foot-second is often used interchangeably with horsepower in certain applications, where 1 horsepower equals approximately 550 lbf·ft/s.

Pound-Foot-Second
power • Non-SI
Definition
The pound-foot-second (lbf·ft·s) is a unit of power in the imperial system, defined as the rate at which work is done when one pound of force is applied over a distance of one foot in one second. This unit is often used in engineering and physics to describe mechanical power, particularly in the context of engines and machinery. The pound-foot-second reflects the relationship between force, distance, and time, and serves as a practical measure for various applications, especially in the United States.
History & Origin
The pound-foot-second system originated from the need for a practical measurement system for work and energy in mechanical contexts. Its roots can be traced back to the early days of engineering when the imperial system was widely adopted in Britain and later in the United States. The combination of pounds, feet, and seconds provides a familiar framework for engineers and technicians working in industrial environments.
Etymology: The term 'pound' comes from the Latin 'pondus', meaning weight, while 'foot' is derived from the Old English 'fōt', a traditional unit of length. 'Second' originates from the Latin 'secunda', referring to the second division of an hour in time.
Current Use
Today, the pound-foot-second is primarily used in the United States and certain engineering fields to quantify power in machinery, engines, and structural applications. It is often referenced in specifications for motors and generators, where it provides a relatable measure for power output and efficiency.
