Significance of 16" Marking on a measuring tape
(OP)
Hello all
Every 16" in a measuring tape has a distinct marking (Either an arrow or a dot) to indicate some thing, what is that? is it some old unit of measurement?

It is 19.2" (19.2" X 5 = 96"), and originally came about with the introduction of wood I-joists, where spacing and spans of joists could be increased. 19.2" for joists and rafters is widely used in residential construction.
Not too common with solid sawn lumber since standard span tables (usually) do not list the 19.2" spacing, however, (most) I-joist manufactures do list this spacing in their standard span tables.
