The kilojoule (kJ) is a unit of energy in the International System of Units (SI). It is defined as the amount of energy transferred when one kilowatt of power is applied for one hour. The kilojoule is widely used in various fields, including nutrition, physics, and engineering, making it an essential unit for energy measurement.
The kilojoule is standardized under the SI system, where it is derived from the joule (J), the basic unit of energy. One kilojoule is equivalent to 1,000 joules. This standardization ensures consistency and accuracy in measurements across different scientific and industrial applications.
The concept of energy measurement has evolved significantly over the years. The joule was named after the English physicist James Prescott Joule, who contributed to the understanding of energy conservation in the 19th century. The kilojoule emerged as a practical unit for expressing larger quantities of energy, particularly in fields such as nutrition, where food energy is often measured in kilojoules.
To illustrate the conversion between kilojoules and other energy units, consider the following example: If a food item contains 2,000 kJ of energy, this can be converted to calories (1 kJ = 0.239 kcal) as follows:
[ 2,000 , \text{kJ} \times 0.239 , \text{kcal/kJ} = 478 , \text{kcal} ]
Kilojoules are commonly used to express energy content in food, as well as in various scientific calculations involving energy transfer, work done, and heat. Understanding kilojoules is crucial for nutritionists, fitness enthusiasts, and engineers alike.

The foot-pound (ft·lb) is a unit of energy or work in the imperial system. It is defined as the amount of energy transferred when a force of one pound is applied over a distance of one foot. This unit is commonly used in various fields, including engineering, physics, and mechanics, to quantify energy, work, and torque.
The foot-pound is part of the British Imperial System and is standardized in various engineering applications. It is essential for ensuring consistency in measurements across different disciplines. The foot-pound is often used in conjunction with other units such as joules and newtons to provide a comprehensive understanding of energy and work.
The concept of the foot-pound dates back to the early days of mechanical engineering and physics. It was developed to provide a practical means of measuring energy in systems that utilized the imperial unit of measurement. Over the years, the foot-pound has remained a vital unit in the engineering community, especially in the United States, where imperial units are still widely used.
To illustrate the use of the foot-pound, consider a scenario where a force of 10 pounds is applied over a distance of 5 feet. The energy expended can be calculated as follows:
[ \text{Energy (ft·lb)} = \text{Force (lb)} \times \text{Distance (ft)} ] [ \text{Energy} = 10 , \text{lb} \times 5 , \text{ft} = 50 , \text{ft·lb} ]
Foot-pounds are commonly used in various applications, including:
