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.

The physical unit "calorie" is the energy required to increase the temperature of one gram of water by 1 degree Celsius, and the dietary Calorie is a kilocalorie = 1000 calories. The dietary Calorie would then raise the temperature of a kilogram of water by 1°C. It is equal to 4186 joules.

A thermometer measures the rise in temperature of the water. Since a Calorie raises the temperature of 1 kilogram (1 liter) of water by 1 degree, the calorie count is found by calculating the change in temperature of the water multiplied by the volume of water. How are calories measured today?

If you're unsure of the difference, we've got answers. Simply put, active calories are those you burn while walking, climbing, jogging — whatever you do for exercise. Total calories include active calories and resting calories, which are those your body burns naturally, even when you're just lounging on the couch.

The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what's commonly called a calorie, so 1,000 calories will be written as 1,000kcals.

A gram of carbohydrate contains 4 calories. A gram of protein also contains 4 calories. A gram of fat, though, contains 9 calories — more than twice the amount of the other two. That's why one food with the same serving size as another may have far more calories.

A calorie is a unit of measure of the energy required to raise the temperature of 1 gram of water by 1 degree C. A joule is a unit of electrical energy, commonly used in the physical sciences, equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second.
