What is a foot-pound?
A foot-pound is an imperial unit of energy equal to the work done when a force of one pound-force acts through a distance of one foot, about 1.356 joules. The foot-pound comes from imperial mechanics and is still used in the US for torque and energy, notably to describe the muzzle energy of firearms and the output of engines.
Common uses of foot-pounds include: Firearm muzzle energy; Torque specifications (as ft·lbf); Mechanical work in imperial units; Engine and tool energy ratings.
What is a kilocalorie?
A kilocalorie equals 1,000 small calories, or exactly 4,184 joules, and is the 'Calorie' shown on food nutrition labels. The food Calorie (capital C) is actually a kilocalorie. This convention, established in nutrition science, means a 500-Calorie meal contains 500 kilocalories, or about 2,092 kilojoules.
Common uses of kilocalories include: Food energy (the dietary 'Calorie'); Metabolism and exercise burn estimates; Nutrition and diet planning; Bomb-calorimetry food testing.
