The ITEM_UNITS_CONVERSION category holds a table of conversion factors between the systems of units described in the ITEM_UNITS_LIST category. The systems of units are identified by a *.from_code and a *.to_code, which are both children of the item _item_units_list.code. The conversion is defined in terms of an arithmetic operator and a conversion factor, _item_units_conversion.operator and _item_units_conversion.factor, respectively.
