Essentially, the difference between calories and kilojoules is terminology - they're two different ways of measuring the energy contained in food and the energy we expend. You can convert calories to kilojoules by multiplying the calories by 4.2.
Kilojoules (kJ), and calories (kcal), are both units that measure energy. Our program uses kcal to measure your energy intake and energy used. If you would prefer, you can convert kcals to kJs by multiplying by 4.18 (100 kcals = 418 kJ). One (1) kilocalorie is the same as one (1) Calorie (upper case C).
What is the difference between calories and kilocalories? The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius.
In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. 1 kJ = 0.2 Cal.
How many kilojoules do I need each day? A kilojoule (like a calorie) is a measure of energy in food. On average, people eat and drink around 8700 kilojoules a day, however we're all different. To maintain your current weight, use your current (actual) body weight in the calculator below.

One kilogram of body fat is equivalent to around 7,700 calories.

The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius. Please visit USDA's Food Composition Laboratory for additional information.
Scientifically, 1 kilocalorie (1000 calories or 1 kcal) means the energy it takes to raise the temperature of 1kg of water by 1 C. That is, 1 Calorie is equivalent to 1 kilocalorie; the capital C in Calories denotes kcal on food labels, calories and kilocalories are used interchangeably to mean the same thing.

Knowing how many kilojoules your body needs each day is important for weight control. The average adult needs about 8,700 kilojoules (kJ). Check how many kilojoules are right for you at this site. Now subtract 2,000kJ off this number.
