What is meant by the least count of an instrument? State the least count of vernier callipers and of a screw gauge.
Original Khojo Papers practice question — not from a past board paper.
Answer
The least count is the smallest measurement that can be read accurately with the instrument. For ordinary vernier callipers it is 0.01 cm and for a screw gauge 0.001 cm.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The least count of vernier callipers is the value of one main scale division divided by the number of vernier divisions.
