kilojulio
Definición: El kilojulio es una unidad de energía derivada del SI (Sistema Internacional de Unidades) que equivale a 1000 julios. El julio se define como la cantidad de energía transferida a un objeto cuando una fuerza de un newton actúa sobre un objeto en la dirección del movimiento a lo largo de una distancia de un metro.
Historia/origen: El kilojulio, al igual que otras unidades derivadas del SI, usa prefijos del SI para denotar múltiplos o submúltiplos de la unidad dada. En este caso, el prefijo "kilo" se usa para expresar un múltiplo de 1000.
Uso actual: En los países que han adoptado el SI, el kilojulio se usa ampliamente como unidad de energía alimentaria. En algunos casos, se muestran tanto los kilojulios como las kilocalorías, aunque en países como los Estados Unidos, solo se muestran las kilocalorías (a menudo denominadas "Calorías") en las etiquetas de los alimentos. Aparte de este uso cotidiano, los kilojulios se utilizan en contextos científicos de todo el mundo.
caloría
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.
