Hi @b.mccarthy. Michael is right. That Enum is pretty basic, and only includes a few basic variations in most measurement types. When you need measurement results in different units than what is available in that Enum, you have to use the String representation of those units. For area & volume type units, there is often a few different ways to format it.
All three of these examples will work for inches cubed: "in*in*in", "in in in", "in^3"
Same applies for Area units: "in*in", "in in", "in^2"
Density then usually needs to include " / " (space "/" space), between the two different units involved, because Density is Mass divided by Volume, and the two use different unit types.
