Convert Kilocalorie (th) to Foot-pound
Please provide values below to convert kilocalorie (th) [kcal (th)] to foot-pound [ft*lbf], or vice versa.
Kilocalorie
Definition: A kilocalorie (symbol: kcal or Cal) is a unit of energy defined based on the calorie and is equal to 1000 calories or 4.1868 kilojoules. A calorie (small calorie) is defined as the amount of energy required to increase the temperature of one gram of water by one °C. Kilocalories are also referred to as large calories or food calories, and are sometimes referred to as Calories, which can be ambiguous, and mistaken for the small calorie.
History/origin: The kilocalorie shares its origin with the small calorie except that it is defined in terms of the kilogram rather than the gram. The term is based on the Latin "calor," meaning heat, and the calorie was first defined as a unit of heat energy in 1824 by Nicolas Clement. The kilocalorie however, was not introduced to the American public until 1887, by Wilbur Olin Atwater.
Current use: Although the kilocalorie is generally considered an obsolete unit, it is still widely used alongside the SI unit of kilojoule to measure food energy. In countries where SI has not been adopted, such as the US, kilocalories, typically referred to as simply "Calories," are still the preferred measurement of food energy. Kilocalories are also sometimes seen in chemistry.
The kilo prefix is based on the SI prefixes, but calories with prefixes beyond the multiple of kilo are not commonly used.
Foot-pound
Definition: A foot-pound (ft·lb or ft·lbf) is a unit of work or energy in the imperial and United States customary systems of units. It is defined as the energy transferred when a force of one pound-force is applied over a linear displacement of one foot.
History/origin: The foot-pound is an English Engineering unit that is part of the British Gravitational system, based on the foot-pound-second (FPS) system. The FPS system is built using the units of foot for length, avoirdupois pound for mass or force, and the second for time.
Current use: The foot-pound is used in countries that have not adopted the International System of Units (SI). The United States is one of the largest countries where the foot-pound is still used in certain applications, though even in the US, the joule is preferred in most scientific contexts.
