A lower-case calorie, or small calorie, is the amount of energy required to heat one gram of water by one degree Celsius. This can vary depending on the temperature of water, but the ISO defines a calorie as 4.184 joules. This unit should not be confused with an upper-case Calorie, or kilocalorie, which is commonly used in food labeling.
A kilojoule is 1,000 joules. In some countries, food is labeled in Kilojoules, much like Kilocalories are used in the United States.
