The switch was just another one of the things that changed when we adopted the SI metric measurement system. Parliament passed the Australian Metric Conversion Act in , and government agencies therefore followed through shortly thereafter. From then on, kids were taught kJ rather than Cal. Even people born after when the big changes happened have stubbornly clung to the old system. A difference, which makes no difference, is not a difference!

Reason 2 — cultural transmission. Australia and New Zealand are arguably the only significant English-speaking countries to have officially opted for kJ over kcal. Healthy people are very focused on them! Furthermore, even the international scientific community has stubbornly refused to give up the calorie. Despite the global adoption of the SI system for science research, it seems that the current method in chemistry is to use kilocalories rather than kilojoules.

Food energy is measured by using a device called a bomb calorimeter. There is an entire specialisation in science known as calorimetry.

Just as there are one thousand joules J in a kilojoule kJ , there are one thousand calories cal in a kilocalorie kcal. This is why some health tools seem to offer wildly different results, depending on whether or not the users are expecting to see kilocalories. Trying to convert 1, calories with one of those converters gives you the result 5 kilojoules, which is obviously wrong 5kJ is what is in one third of a gram of Weet-Bix. To make things even more confusing, when most people talk about calories, they really mean kilocalories!

That is, kcal or Cal rather than cal. The formula to change kilojoules to calories is quite simple. Since one Cal is equal to 4. Dividing by 4. At Calorie Counter Australia, we insist on using the more precise 4. Most of our energy comes from the macronutrients macros , namely carbohydrates including sugar , fat, and protein in food we eat.

In this case, the prefix "kilo" is used to express a multiple of Current use: In countries that have adopted SI, the kilojoule is widely used as a unit of food energy.

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. Definition: A kilocalorie symbol: kcal or Cal is a unit of energy defined based on the calorie and is equal to calories or 4.
