Food labels list the amount of carbohydrates. If the food is cut in half, is the carbohydrate cut in half?

On the new food labels, it lists the number of carbohydrates per food serving. If the food serving is cut in half, does that mean the amount of carbohydrate will be cut in half as well?

The amount of carbohydrates listed on the Nutrition Facts food label on food packages is the number of carbohydrates in one serving of food as specified on this same label. So if you eat half a serving, you get half the carbohydrates as well as half all the other nutrients.
