BSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). Here are the actual thread dimension data for BSPP and BSPT threads. The major diameter is a bit larger smaller than the actual OD of the pipe, and the minor diameter should be very close to what you would measure inside the

The main difference between NPT and BSP threads is that the thread angle in NPT threads is 60 degrees while that of BSP pipes is 55 degrees. BSP threads are usually straight/parallel while NPT threads are usually tapered. If the threads are the same size then it is BSP whereas if the first thread is small (in diameter) that the last then it

To find the thread size: 1) Measure the O.D (Outer diameter) of the BSP thread. 2) Take the O.D measurement in inches and subtract 1/4 (.25″). For example, a BSP parallel male thread measures out to O.D 1″. Subtracting 1/4 gives a thread size of 3/4 also known as "dash" 12.

Likewise, pipe thread can be parallel (e.g., BSPP). For pipe thread, determine the size by comparing it with a nominal size profile, as shown in Figure 1 (a useful tip - pipe sizes up to 2" nominal size can be determined by measuring the actual outside diameter, subtracting ¼" then rounding-off).
