Kilojoules (kJ)
Definition
A kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used for expressing larger quantities of energy in nutritional contexts and engineering.
History
The kilojoule naturally derives from the joule with the SI kilo- prefix. It gained widespread use in the 20th century, particularly in countries adopting the metric system for food energy labeling.
Current use
Kilojoules are the primary energy unit on food labels in Australia, New Zealand, and many European countries. They are also used in heating, ventilation, and chemical energy calculations.
Foot-pounds (ft⋅lb)
Definition
A foot-pound (ft⋅lb) is an imperial unit of energy equal to the work done when a force of one pound-force moves an object one foot. It equals approximately 1.35582 joules.
History
The foot-pound has been used in English-speaking countries since the early days of mechanical engineering. It was the standard unit for torque and mechanical work before the joule gained prominence.
Current use
Foot-pounds are widely used in the US for measuring torque in automotive and mechanical applications, firearm muzzle energy, and mechanical work in engineering specifications.
