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 Hourlf·h
Target UnitThe pound foot hour (lf·h) is a unit of power that quantifies the rate at which work is performed. Specifically, it represents the amount of work done when a force of one pound acts over a distance of one foot in one hour. As a non-SI unit, it is primarily used in certain engineering and mechanical contexts. The calculation involves the work-energy principle, where power is the work done divided by the time taken. Thus, 1 lf·h is equivalent to 0.00181 horsepower. This definition highlights the significance of both work and time in determining power output.
Current Use
The pound foot hour is commonly used in fields such as mechanical engineering, automotive engineering, and various industrial applications where power output needs to be quantified in imperial units. Although less prevalent than SI units, it remains relevant in the US, particularly in the context of machinery and equipment specifications. Its use in automotive power ratings and in some engineering calculations highlights its importance in practical applications.
Fun Fact
The pound foot hour is closely related to the imperial measurement system, which is still widely used in the United States.

Pound Foot Hour
power âą Non-SI
Definition
The pound foot hour (lf·h) is a unit of power that quantifies the rate at which work is performed. Specifically, it represents the amount of work done when a force of one pound acts over a distance of one foot in one hour. As a non-SI unit, it is primarily used in certain engineering and mechanical contexts. The calculation involves the work-energy principle, where power is the work done divided by the time taken. Thus, 1 lf·h is equivalent to 0.00181 horsepower. This definition highlights the significance of both work and time in determining power output.
History & Origin
The pound foot hour emerged from the imperial system of measurement used in the United States and the UK, evolving from older systems that used pounds and feet to quantify work and energy. Its use is primarily associated with mechanical and engineering applications, particularly in the context of rotating machinery and engines where power output is crucial. The necessity to quantify power in familiar terms led to the adoption of the pound foot hour as a practical unit.
Etymology: The term 'pound' derives from the Latin 'libra', which refers to a weight measure, and 'foot' comes from the Old English 'fĆt', indicating a length measure. 'Hour' is derived from the Latin 'hora', which signifies a unit of time.
Current Use
The pound foot hour is commonly used in fields such as mechanical engineering, automotive engineering, and various industrial applications where power output needs to be quantified in imperial units. Although less prevalent than SI units, it remains relevant in the US, particularly in the context of machinery and equipment specifications. Its use in automotive power ratings and in some engineering calculations highlights its importance in practical applications.
