'''Tenacity''' is the customary [[measure]] of strength of a fiber or yarn. In the U.S. it is usually defined as the [[ultimate]] (breaking) strength of the fiber (in gram-force units) divided by the [http://en.wikipedia.org/wiki/Units_of_textile_measurement#Denier denier].

Because denier is a measure of the linear density, the tenacity works out to be not a measure of force per unit area, but rather a quasi-[[dimension]]less measure [[analogous]] to [http://en.wikipedia.org/wiki/Specific_strength specific strength].
