Calories Counting Calories are units of energy so small that a single apple provides thousands of them. To ease calculations, energy is expressed in 1000-calorie units known as kilocalories (shortened to kcalories, but commonly called calories). When you read that an apple provides "100 calories," that actually means 100 kcalories. The abbreviation for the term kcalorie is kcal and is used in many scientific books and journals. Think Metric Most food labels and many recipe books provide "dual measures" listing both household measures, such as cups, quarts and teaspoons, and metric measures, such as milliliters, liters and grams. This practice gives people a chance to gradually learn to "think metric." It All Adds Up Many members of the international scientific community have adopted a common system of measurement , which is known as the International System of Units (SI). For example, the SI unit for measuring food energy is the joule (not the kcalorie). While many scientists and journals report their findings in kilojoules (kJ), many others, particularly those in the United States, use kcalories. To convert energy measures from kcalories to kilojoules, multiply by 4.2. For instance, a 50-kcalorie cookie provides 210 kJ: 50 kcal x 4.2 = 210 kJ. Menu Measurements Select all the items you would be likely to eat at the fair and find out your total kcalories and kilojoules.
