Pitch = Distance moved / Number of complete rotations and Least Count = Pitch / Number of divisions on head scale.
Explanation:
- Pitch is the smallest value of length or any other unit which can be read directly from a main scale accurately.
- Least count is the magnitude of the smallest measurement that can be measured by an instrument accurately.
- The pitch is the distance between the threads, so, can determine this number by measuring the number of threads per inch or centimeter on the screw, then divide one by the number of threads.
- Pitch = 1 ÷ number of threads per inch or cm.
- For example, if a screw has eight threads per inch, the pitch is 1/8.
