Is kcal the same as calories?
The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (uppercase C). A kilocalorie is the amount of heat required to raise the temperature of one kilogram of water one degree Celsius.
What means kcal?
kilocalorieScientifically, 1 kilocalorie (1000 calories or 1 kcal) means the energy it takes to raise the temperature of 1kg of water by 1°C.
How many J is 1kj?
One kilojoule is equal to 1,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter. The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for 103.

How is kcal calculated?
The Calorie you see on a food package is actually a kilocalorie, or 1,000 calories. A Calorie (kcal) is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius. Sometimes the energy content of food is expressed in kilojoules (kj), a metric unit. One kcal equals 4.184 kj.

How many joules are in a kilojoule?
Kilojoule. Definition: The kilojoule is an SI (International System of Units) derived unit of energy that is equal to 1000 joules. The joule is defined as the amount of energy transferred to an object when a one newton force acts on an object in the direction movement through a distance of one meter. History/origin: The kilojoule, like other SI ...
Where did the term "kilocalorie" come from?
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.
What is a calorie?
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 ...
What is the meaning of the SI prefix "kilo"?
In this case, the prefix "kilo" is used to express a multiple of 1000. Current use: In countries that have adopted SI, the kilojoule is widely used as a unit of food energy.
Is kilocalorie the same as kilojoule?
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.
Do kilocalories show on food labels?
In some cases, both kilojoules and kilocalories are displayed, though in countries such as the United States, only kilocalories are shown (often referred to as "Calories") on food labels. Aside from this everyday use, kilojoules are used within scientific contexts around the world.
