All ingredients in ClassCart have a set of measurement methods that determine how they are ordered and collated. There are three measurement methods in ClassCart—Weight, Volume, and Discrete Units—and an ingredient can be measured in any combination of the three.

Discrete units are custom and will vary from ingredient to ingredient. For example eggs may have an "each" unit and a "carton" unit. One "carton" would convert to 12 "each".

The Weight measurement has 3 units: milligrams, grams, and kilograms. Here is a conversion table for units of weight:

The Volume unit has 5 units: millilitres, teaspoons, tablespoons, cups, and litres. Here is a conversion unit for units of volume:

Ingredients can and should be measured in any combination of these methods that is appropriate. A great example of this would be ingredients that come in packets such as Chocolate. It can be measured by Weight, but also have a discrete "Packets" unit with a conversion of something like 180 grams.

Once the measurements are set, ClassCart is then able to automatically make the conversions for you when you order, add to recipes etc. saving you so much time.

For ingredients that are measured in both Weight and Volume units (spices etc.), a density will need to be provided for accurate conversions. ClassCart has a list of densities for common ingredients, but if your ingredient is not in this list you will have to find the density somewhere else.

A quick way to get an ingredient's density is to use a conversion you know for that ingredient. For example, if you know that 1 cup of the ingredient is 250 grams, you can increase or decrease the density number until you have the correct conversion:

If you don't know a quick conversion, a good website to find ingredient densities from is aqua-calc.com/page/search. Search for your ingredient and then click on a link starting with "Density of..."
