Step 1: Understand the relationship between Calories and kilojoules. 1 Calorie (with an uppercase 'C', also known as a kilocalorie) is equivalent to 4.184 kilojoules.
Step 2: Identify the given information. The problem states that a Big Mac contains 540 Calories.
Step 3: Set up the conversion from Calories to kilojoules using the conversion factor from Step 1. Multiply the number of Calories by the conversion factor (4.184 kJ/Calorie).
Step 4: Perform the multiplication to convert the energy content from Calories to kilojoules. This involves multiplying 540 by 4.184.
Step 5: Interpret the result. The product from Step 4 will give you the energy content of the Big Mac in kilojoules.
