Tit-hair 

(‘tît hār) Noun. English (American).

A universally accepted unit of measurement that is equal to 1/10,000th of the width of the mark on your ruler that denotes a millimeter.

The tit-hair is a “Special” unit of measurement (akin to the pinch, dash, or dab) that can be applied universally to both the Metric system and the “American” system with no conversion factor. It can also be used with ANY measurement: distance, weight, volume, mass, density, temperature, etc., without a conversion factor.

Origin: approx 1948-1950 - Returning GI’s from WWII had invented the term as they were fine tuning their weapons. From rifles to tanks to artillery - this is how it developed such universal adaptation.

You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
