About this document
Understanding Threading Units: Metric & BSW by Malik Ali is a document available to read on EtoBox.
The document discusses two systems for units of threading - the metric system and the Whitworth/BSW system. The metric system uses meters and millimeters as units, and dimensions are written as diameter x pitch (e.g. M18 x 2.5). The Whitworth/BSW system uses inches and fractions of inches as units, with dimensions written as a fractional ratio (e.g. 1/2-13). Both systems define the pitch as the distance between threads.
