Conversion Of Kcal To Joules

Convert cal to J

Please provide values below to catechumen calorie (th) [cal (th)] to joule [J], or vice versa.

calorie

Definition: A calorie (symbol: cal) is a unit of energy defined every bit the amount of free energy required to increase the temperature of one gram of water by one °C. This is referred to equally the pocket-sized calorie or the gram calorie, and is equal to four.1868 joules, the SI (International System of Units) unit of measurement of energy.

A large calorie (symbol: Cal), also known equally a kilogram calorie (symbol: Cal), is technically a kilocalorie (symbol: kcal), the equivalent of 1000 small calories, but is also sometimes referred to equally simply "Calorie." Large calories are usually used for labeling foods, and as such, is known equally the food calorie.

History/origin: The term calorie comes from the Latin word "calor," which ways heat. It was commencement defined every bit a unit of heat energy in 1824 by Nicolas Clement and appeared in French and English dictionaries betwixt 1841 and 1867. The large calorie was introduced to the American public later, in 1887, past Wilbur Olin Atwater.

Electric current apply: Although the calorie can be used with SI, since the official adoption of SI in 1960, the calorie is considered obsolete. Despite this, the big calorie is notwithstanding widely used as a unit of food energy, aslope, or in place of the SI unit of measurement 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 still, resulting in some defoliation when foods are only labeled as Calories rather than kilocalories.

Calories are as well used inside scientific contexts, such as chemistry. In these contexts, the term beingness referenced is nearly often the small calorie, though measurements are often reported in kilocalories.

Joule

Definition: A joule (symbol: J) is a derived unit of energy in the International Organisation of Units (SI). It is defined every bit the energy transferred to an object when a one newton force is applied to the object in the direction of its motility through a distance of 1 meter. It is also defined as the energy dissipated every bit heat when a 1 ampere electric current passes through a resistance of i ohm in the course of one 2nd. It has a number of representations both in SI base units also as other SI units such that:

J = kg·g^two/sⁱⁱ = North·m = Pa·one thousand³ = W·s = C·V

History/origin: The unit of measurement, joule, is named subsequently James Prescott Joule, an English physicist and mathematician who helped develop the Kelvin scale. He also discovered the human relationship between heat and mechanical work, leading to the constabulary of conservation of free energy, and subsequently, the kickoff law of thermodynamics.

Electric current use: Every bit an SI derived unit, the joule is used inside a variety of scientific contexts. Practical examples of energy measurement using joules include the energy required to lift objects, the energy released when objects fall, the heat required to raise temperature, and the kinetic energy of moving objects.

One of the dimensional representations of a joule is the N·k (Newton-meter), which is equivalent to the SI unit for torque. These units nonetheless, are different, and should be considered as such. Fifty-fifty though the joule is algebraically equal to the N·yard, the Due north·chiliad should not exist used to represent the joule whenever possible, to avoid defoliation with torque.
