NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1

The unified thread standard has three distinct variances called Unified Coarse Thread (UNC), Unified Fine Thread (UNF), and Unified Extra Fine Thread (UNEF). The difference between the three is the amount of threads per inch. For example, a 1 inch fastener size in UNC has 8 TPI, in UNF 12 TPI, and 20 TPI in UNEF).
