Metric threads are called that way, because you measure the distance between the threads (at the highest point), in millimeters., As opposed to SAE (standard), which are measured by the number of threads in an inch.
A .75-10 Unified National Coarse thread (3/4-10 UNC) has 10 threads per inch. The lead would be 1/10 of an inch.
Thread series cover designations of diameter/pitchcombinations that are measured by the number of threads per inch (TPI) applied to a single diameter
The pitch of a bolt is the distance between threads measured along the bolt's axis. It can be calculated using the formula: Pitch = Distance between two adjacent threads. For metric bolts, the pitch is typically given in millimeters, while for imperial bolts, it is often measured in threads per inch (TPI). To convert TPI to pitch, use the formula: Pitch (inches) = 1 / TPI.
yes, length is measured anywhere the paintball is inside the barrel
Standard thread are meassured in number of threads per inch (example 1/4-20) 1/4 inch dia. bolt with 20 threads per inch. Metric threads are measured in mm between thread (M8 x 1.5), an 8 MM bolt with a thread pitch of 1.5MM between threads.

Atomic mass is measured by atomic mass unit(amu) . It is given by 'u' i.e. unified mass.
UNC= American Standard (unified course thread)It is a bolt that has 13 threads per inch. which would be a 1/2 in in diameter bolt which has a unc of 13Titan, Superior Bolting Solutions
No, NPT threads are not compatible with NPSM threads. A pipe with NPT threads tapers slightly, while an NPSM-threaded pipe does not taper.
There are two main kinds of threads implementations: User-space threads and Kernel-supported threads. Mikaela
Plumbing pipe threads are squared and conduit pipe threads are tapered.
