Each item in our database displays all applicable serving types. If you cannot find the particular serving type for the chosen item, that means we weren't able to figure this out.
There are two groups of standard measurement units: volume and weight. Some food labels have just 'weight' information, others just 'volume,' whereas the third ones may have both serving weight and serving volume.
The standard food weight measurement units are grams and ounces. There are five food volume measurement units: milliliters, teaspoons, tablespoon, fluid ounces, and cups. The system uses the US (Imperial) converter between tsp, tbsp, oz, fl oz, and cup, depending on the user's setting to use or not use metric units. However, we still show all other available serving types according to the vendor's info. We do not exclude any measurement units after conversion.
If you see one of the five 'volume' units of measurement, you will find the remaining four in the serving suggestions of this food. For example, if you see "ml," you will see the "cup," "tbsp," "fl oz," and "tsp" as well. The app does the necessary conversion of the nutrition facts between these five 'volume' servings automatically.
If the vendor provided the serving weight in grams, the system would also display the equivalent in ounces (and vice versa).
You may wonder if we could estimate rough conversion between 'volume' and 'weight' when the vendor refuses to provide enough information. We could show more serving types after that. Theoretically, to get the connection between 'weight and 'volume' and to have more serving types in serving suggestions, we could interchange "g" and "ml," "oz," and "fl oz." The conversion error would be insignificant in some cases; especially, if you have a kitchen scale. Unfortunately, we cannot add all 'weight' and 'volume' serving suggestions to our foods. A conversation between mL and gram is not always genuine. There is no way to make such a conversion without knowing the density of the item. And the vendor does not provide info about food density. An example is "table salt" and "popcorn." A milliliter of "salt" will weigh heavier than a gram, and a milliliter of "popcorn" will weigh lighter than a gram. The "fl oz" unit is not always equal to "oz" for these foods. We agree that in many items, they are pretty close (e.g., "water" and "coca-cola.") But, we have a lot of mixed foods (e.g., frozen combo dinners, sandwiches, and so on.) So, we cannot show the units of 'volume' measurements if the vendor did not provide the nutrients for at least one serving in a 'volume' measurement. (Or, if the vendor does not show the nutrition facts for at least one unit of the 'weight' measurement.) In some cases, we cannot "convert," estimate, or get the approximate values for the missing unit of measure you may want or need.
We strive to display as many units of measurements as possible. Some of our items have 'volume' and 'weight' units for portion choice; e.g., "water tap drinking" has both. Some foods have just 'weight' serving suggestions; for instance, "carrot raw." Others have just 'volume' in serving suggestions; see the "Milk 2% fat with vitamins a & d by jewel" item; it does not have "g" or "oz" in servings.
We cannot estimate the 'weight' info when the vendor does not provide at least one 'weight' serving description. And, we cannot add and assess ourselves the 'volume' if the vendor does not give us at least one 'volume' description for this product. We regret any inconvenience that this might have caused.
As a suggestion, search for the generic item, (Staple Foods;) they have the complete nutrition facts and vary standard servings.
Alternatively, use the "copy & customize" feature and create your custom food based on the original item with the missing serving type.
