Answer :
Answer:
Least Count (LC) of a screw gauge is calculated as:
LC = Pitch / Total number of divisions on the circular scale
Given:
Pitch (p) = 0.5 mm
Total number of divisions = 50
Least Count (LC) = p / 50
= 0.5 mm / 50
= 0.01 mm
= 0.01 cm
= 0.001 cm
So, the Least Count of the screw gauge is 0.01 mm or 0.001 cm.
