Convert Newton Meter to Kilocalorie (th)
Please provide values below to convert newton meter [N*m] to kilocalorie (th) [kcal (th)], or vice versa.
Definition: The newton-meter (N·m) is sometimes used as a unit of work or energy and in this context is equal to the joule, the SI unit of energy. In this use, it is defined as the energy transferred to an object by a one newton force acting on that object in the direction of its motion over a distance of one meter.
History/origin: The use of the newton-meter as a unit of work or energy is derived from the fact that the joule, the SI (International System of Units) unit of energy, is dimensionally equivalent to the newton-meter.
Current use: The newton-meter is more commonly used as a unit of torque rather than as a unit of work or energy. As such, the use of the newton-meter as a unit of work or energy is discouraged to avoid confusion regarding whether energy or torque is being expressed.
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.
