Convert calorie (nutritional) to j
Calorie (Nutritional)
The nutritional calorie (symbol: Cal, also written kcal) is a unit of energy equal to one kilocalorie (4,186.8 joules), used to quantify the energy content of food and beverages. It is defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. Despite being a non-SI unit, the nutritional calorie remains the standard unit for dietary energy worldwide.
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
