In the Unit of Measures Overview, we are asked to find out what is the corresponding unit for the US Customary UOM group. The answer given is: Either yard or food (ft).
Is there a faster way to find the answer? One way that I found out is to go through the entire list of unit and look at the UOM group mappings from properties. Both ft and yard shows m under the Metric group. However, when I am looking at the properties for m, it only shows yard under the US customary group.
