Serving sizes are standardized on food labels to make it easier to compare similar foods; they are provided in familiar units, such as cups or pieces, followed by the metric amount, e.g., the number of grams.
Both describe food serving sizes. The Food Pyramid assigns a portion size to each serving, then recommends how many of these servings from each food group you should eat daily for a balanced diet. Food labels offer a slightly different standardized serving size to be used when shopping to compare nutritional information between similar products.

Calcium is normally listed in milligrams on nutritional labels.
Wine bottles have labels for a variety of reasons. They tell consumers what type of wine it is (red or white), the name of the wine, where and when the wine was bottled.

Nutritional labels on food are not "based" on calories, they are normally based on serving size. It will say something like "Serving Size 1 ounce" then tell you how many calories, sugars, etc are in that 1 once.
One reason serving sizes are standardized (example: 1 cup) is to make it easy for consumers to compare foods before buying. Image you have $5.00 and you buy macaroni, expecting 4 cups within the package, with a 1 cup serving size. But when you get home, you take a measuring cup and find that the expected "1 cup serving" is more like 1/2 cup instead. Wouldn't you feel cheated? More so, though, serving size is standardized among similar products so that a comsumer can check the calories and various nutrients listed for "one serving". Let's say you buy cereal. Each says a serving is 1/2 cup (you don't count the milk or anything you add to the bowl). But Product A says calories are 250, and Product B lists 330 calories. That's a big difference if you are counting calories or need to lose weight. You look further at the ingredients and one manufacturer lists sodium 20 grams; a different product lists 35 grams. Again, 15 grams is a big difference and the extra sodium can have negative health consequences, even if the cereal is supposed to be good for health. Discrepancies like this have come more and more to the attention of the FDA which requires truthful labeling on packages. Most wise consumers often read labels and do food ingredient comparisons to make sure they buy not only the best product, but the best for their health and money spent.
The fastest way to know how much is in a single serving is to read the ingredient labels on the boxes. If the labels says that 5 crackers, or is a single serving. then you have the answer. Some boxes will say that they contain 2 1/2 servings, so then you know that each serving should be half of that figure.
Nutrition labels must be read carefully to ensure that you are getting the correct amount of calories. The labels will give a serving size and the amount of servings provides. If you eat two granola bars and the serving size is for just one bar then you must double the amount of calories to determine how many total calories were ingested. The food and drug administration regulates nutrition labels and by going to their web site, you can find out how to properly read a nutrition label.
If serving sizes are given, they are normally on the "nutritional information" label - it will break it down into an analysis per 100g, and then per portion. However not all canned foods state serving sizes.
