In business, handling products in different units of measure is very important and
it's very essential to sell and buy products in different quantities that are convenient
for consumers. Units of measures are an indication citing the unit used to handle
a particular product. Thus the concept- Unit of measure arises from purchasing a
product either in bulk or in fewer quantities.
Unit of Measure (UoM) refers to which units the products are sold and purchased,
while the Unit of Measure Category refers under which category those units are coming.
Here one unit can be converted to another only when they belong to the same category.
