To determine the percentage of total kilocalories from carbohydrates in the nutrition facts of a cereal, you need to look at the total calories and the calories derived from carbohydrates. First, find the number of grams of carbohydrates and multiply that by 4 (since each gram of carbohydrate provides 4 kilocalories). Then, divide the kilocalories from carbohydrates by the total kilocalories and multiply by 100 to get the percentage. For example, if a cereal has 200 total calories and 30 grams of carbohydrates, it would have 120 calories from carbohydrates, making it 60% of total calories.
