Ends per inch (EPI or e.p.i.) is the number of warp threads per inch of woven fabric. [12] [22] In general, the higher the ends per inch, the finer the fabric is. Ends per inch is very commonly used by weavers who must use the number of ends per inch in order to pick the right reed to weave with. The number of ends per inch varies on the ...

The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.

Microphone stands: 5 ⁄ 8-inch 27 threads per inch (TPI) Unified Special thread (UNS, USA and the rest of the world)
Picks per inch is the number of weft threads per inch of woven fabric. [5] Pick is a term that refers to a single weft thread. [6] By and large, the more ends and picks per inch, the finer the cloth. Balanced plain weave fabrics have warp and weft threads that are the same weight (size) and have the same number of ends and picks per inch. [7]
Cotton bolts are traditionally 42 inches (1.067 meters) wide and wool bolts are usually 60 inches (1.524 meters) wide. Thus a bolt of cotton is 116.667 square yards (97.566 m2) and a bolt of wool is 166.667 square yards (139.355 m2). Sarkar, Prasanta. Garment Manufacturing: Processes, Practices and Technology.

The term fine adjustment screw typically refers to screws with threads from 40–100 TPI (Threads Per Inch) (0.5 mm to 0.2 mm pitch) and ultra fine adjustment screw has been used to refer to 100–254 TPI (0.2 mm to 0.1 mm pitch). These screws are most frequently used in applications where the screw is used to control fine motion of an object.
The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm). The optional UNC specification indicates the standard coarse thread is used which is defined for #6 screws as 32 tpi rendering 'UNC ...
