You can cross-reference the bore size on the following chart with thread pitch and threads per inch to find your desired size and its related specs. BSPT-tech.

There are two types of BSP Thread available. One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD- Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD - Thread form per AS 1722.1, BS 21, ISO 7.

BSPT & BSPP Threads Dimensions. Thread size refers to the nominal bore of the pipe. Subtract approx. 1/4″ (6mm) from thread diameter measurement for nominal pipe size. Pitch is Threads

BSP Thread Type - British Standard Pipe This is a standard thread type that has been adopted internationally for interconnecting and sealing pipe ends. You'll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. BSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads.

This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. BSP parallel threads commonly seal via a 30° chamfer on the male thread to a 30° 

External Pipe Threads per. ISO 228-1, Pipe threads where pressure-tight joints are not made by the threads. These pipe threads are also known as Whitworth pipe threads.

NPTF, BSPT and BSPP measure 1/4" larger than their actual size. For example, a 1/4" NPTF, BSPT or BSPP will actually measure 1/2" on the O. D. of the threads. JIC, SAE O-ring & Flat Face threads measure as listed below. The first number listed is the size of thread, the second number is the threads per inch. Adapter Sizing Chart Thread

NOTE: It is a common mistake to identify a BSPT (tapered) as an NPT. Remember that NPT threads have a 60° thread flank angle, and BSPT has a 55° angle (this can be verified with a thread gauge). Although BSP is a foreign thread, it isn't metric. This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. Thread conforms to ISO 228-1.
