What is the fuel value in kg in a 42g serving of a pound of plain M and Ms?

A pound of plain M&Ms weighs approximately 453.6 grams. If a serving is 42 grams, you can calculate the fuel value (calories) per serving based on the nutritional information. Plain M&Ms typically have around 4.8 calories per gram, so a 42g serving would contain approximately 201.6 calories. To convert calories to fuel value in kg, you would need to know the energy density of the fuel source being compared, but generally, the focus is on caloric content for food.
