Unit Explanations
KilowattkW
Source UnitA kilowatt is a unit of power that is equivalent to 1,000 watts. It is widely used to measure the rate at which energy is used or generated. The kilowatt is part of the International System of Units (SI) and is often used for expressing the output power of engines and the power consumption of electric appliances. In the context of electrical power, one kilowatt is equal to the energy conversion or transfer of one thousand joules per second. It is a commonly used unit in many areas, including electrical engineering, physics, and everyday electricity billing.
Current Use
Today, kilowatts are used worldwide in numerous industries, including electricity generation, automotive, and manufacturing. It serves as a standard measurement for power output and consumption. Electric utilities use kilowatts to bill residential and commercial customers. The kilowatt also plays a crucial role in energy efficiency discussions as it allows for the comparison of the power consumption of various devices and systems.
Fun Fact
A single kilowatt can power ten 100-watt light bulbs.
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.

Definition
A kilowatt is a unit of power that is equivalent to 1,000 watts. It is widely used to measure the rate at which energy is used or generated. The kilowatt is part of the International System of Units (SI) and is often used for expressing the output power of engines and the power consumption of electric appliances. In the context of electrical power, one kilowatt is equal to the energy conversion or transfer of one thousand joules per second. It is a commonly used unit in many areas, including electrical engineering, physics, and everyday electricity billing.
History & Origin
The concept of the kilowatt emerged as technology evolved and the need for measuring power became more prevalent. The kilowatt was officially adopted as part of the International System of Units in 1960. It originates from the watt, named after James Watt, a Scottish inventor who made significant improvements to the steam engine in the 18th century. The kilowatt thus became a convenient way to express power on a larger scale, particularly as electrical power generation and consumption expanded.
Etymology: The term 'kilowatt' combines the prefix 'kilo-', meaning a thousand, with 'watt', the SI unit of power named after James Watt.

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.
