Convert from iron to stick

Unit Definition (iron)
The iron is a traditional unit measuring the thickness of leather used in making shoes, especially the soles of the shoes. One iron is equal to 1/48 inch (0.5292 millimeter), so a sole 1/4 inch thick is described as "12 iron".

Unit Definition (stick)
A stick, when used as a unit, is usually two inches, i.e. 5.08 cm (for the international inch). It was once used in the English tailoring business, but has since fallen out of use completely.
