Variable mass units of measure
Some volumetric measures, like cup or package, do not account for the mass of various items. For example, the mass of one package of carrots does not equal the mass of one package of lettuce.
| Mass of 1 package of carrots |  |
Mass of 1 package of lettuce |
A single item cannot account for various forms of the item that each have a different mass.
| 1 cup of carrots, whole | |
1 cup of carrot, sliced | |
1 cup of carrots, shredded | |
1 cup of carrots, mashed |
Instead of specifying multiple units of measure, you can keep the same unit of measure. For example, you can specify CUP and use the parameter type 16 Variable UOM to create a parameter for each variation. (The variations are CUP-WHOLE, CUP-SLICED, CUP-SHREDDED.)
The parameter stores the mass for different forms of an item. For example, CUP-SLICED for carrots =.24 KG; CUP-SHREDDED for carrot =.306 KG.
When carrots are added to a formula, the variable unit of measure is selected, (e.g., CUP-SLICED or CUP-SHREDDED). The associated parameter value is used to calculate the variable mass.
