It is not really dual scaling but dual labeling. The line marks are the same
for metric and tsp just labeled in familiar if not appropriate verbiage. One
can assume (maybe someone should check it) that the lines are set for ml and
labeled for tsp and not vise versa (i.e. it's defined in metric).
dual scaling in non-metric and metric units, as the majority of U.S.
dosing cups seem to be doing

Subject: [USMA:53405] Delsym 12-Hour Cough Relief liquid dosing cup
As told to me on the product's consumer hotline, the dosing cup (right) for
this over-the-counter cough liquid is marked off in milliliters only. This is
among the first occurrences of exclusively metric measurement in a U.S.-
marketed nonprescription remedy. The "Drug Facts" label on Delsym products also
excludes mention of non-metric units of volume, and includes the statement "mL
= milliliter," suggesting that the manufacturer wishes to make these
measurements metric-oriented. The dosing cup on the left , which came from a
generic antihistamine liquid product, retains the dual scaling in non-metric
and metric units, as the majority of U.S. dosing cups seem to be doing, at
least according to my recent patrol of the OTC liquid medication aisle at two
local chain outlets.
