The least count of a vernier caliper is the smallest measurement it can accurately read, typically 0.02 mm or 0.01 mm.

• The least count is determined by the smallest division on the main scale and the number of divisions on the vernier scale.

• For a standard vernier caliper with 10 divisions on the vernier scale and 1 cm on the main scale, the least count is 0.1 cm - 0.09 cm = 0.01 cm or 0.1 mm.

• In some vernier calipers, th...read more

The least count of a micrometer is the smallest measurement it can accurately read, typically 0.01 mm or 0.001 cm.

• A standard micrometer has a least count of 0.01 mm.

• This means it can measure dimensions with precision up to 0.01 mm.

• For example, if a micrometer reads 5.25 mm, it can accurately measure between 5.24 mm and 5.26 mm.

• Some specialized micrometers may have a least count of 0.001 mm for higher precision.
