How do you measure 1/4 inch BSP?
The easiest way is to count the thread crests over a shorter length, say 1/4″, and simply multiply it by 4. For example, if you count 3.5 thread crests over 1/4″: 3.5 x 4 = 14 threads per inch. Take this measurement and cross-reference it to your thread size in the chart below.
