Premise: uh and little things like that i i notice in a lot of uh uh technical literature that you pick up and catalogs and so forth that you will find the metric units expressed in parenthesis or sometimes the other way around the metric units are expressed first and then the English equivalent that's uh is put into parenthesis for reference

Hypothesis: Most technical literature only includes metric units or the English equivalent, never both at the same time.
Relation: contradiction
