How to calculate thread pitch

Pitch refers to the distance between adjacent peaks of threads, and it is crucial for the fit and function of threads. There are two common methods for calculating pitch: for metric threads, pitch usually refers to the distance between two threads, measured in millimeters; for imperial threads, pitch is typically expressed as "threads per inch" (TPI), meaning the number of threads in one inch. For metric threads, measuring the distance between adjacent threads gives the pitch; for imperial threads, the pitch is determined by calculating how many threads there are per inch.
