Convert Calorie (th) to Newton Meter
Please provide values below to convert calorie (th) [cal (th)] to newton meter [N*m], or vice versa.
Definition: A calorie (symbol: cal) is a unit of energy defined as the amount of energy required to increase the temperature of one gram of water by one °C. This is referred to as the small calorie or the gram calorie, and is equal to 4.1868 joules, the SI (International System of Units) unit of energy.
A large calorie (symbol: Cal), also known as a kilogram calorie (symbol: Cal), is technically a kilocalorie (symbol: kcal), the equivalent of 1000 small calories, but is also sometimes referred to as simply "Calorie." Large calories are usually used for labeling foods, and as such, is known as the food calorie.
History/origin: The term calorie comes from the Latin word "calor," which means heat. It was first defined as a unit of heat energy in 1824 by Nicolas Clement and appeared in French and English dictionaries between 1841 and 1867. The large calorie was introduced to the American public later, in 1887, by Wilbur Olin Atwater.
Current use: Although the calorie can be used with SI, since the official adoption of SI in 1960, the calorie is considered obsolete. Despite this, the large calorie is still widely used as a unit of food energy, alongside, or in place of the SI unit of food energy, the kilojoule. The use of a capital "C" in Calorie is intended to denote the use of kilocalories rather than calories denoting a single calorie. This is not often understood however, resulting in some confusion when foods are only labeled as Calories rather than kilocalories.
Calories are also used within scientific contexts, such as chemistry. In these contexts, the term being referenced is most often the small calorie, though measurements are often reported in kilocalories.
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.

How to Convert Calorie (th) to Newton Meter
1 cal (th) = 4.184 N*m
1 N*m = 0.2390057361 cal (th)
Example: convert 15 cal (th) to N*m:
15 cal (th) = 15 × 4.184 N*m = 62.76 N*m
