If you mean the metric subdivisions, I suggest you search for "SI prefixes". Some extremely small prefixes are used, but they would normally not be used in your daily life for measuring lengths. The smallest divisions that are normally marked on a meter scale are the millimeters.
The least count of a half meter scale is 0.5 cm. This means that the smallest measurement that can be accurately obtained using the scale is 0.5 cm.
The least count of a half meter rod is 0.5 cm. This means that the rod can be measured in increments of 0.5 cm, allowing for precise measurements.
The least count of a physical balance is the smallest measurement that can be read or displayed on the balance scale. It is determined by the precision of the scale and the smallest division marked on the scale or indicated by the scale's display.
The least count of a screw gauge is calculated by dividing the pitch of the screw by the number of divisions on the circular scale. The formula is Least Count = Pitch / Number of divisions on the circular scale.
The least count of a thermometer scale is the smallest temperature difference that can be measured by the scale. It is typically based on the precision of the markings on the scale, which can vary depending on the design and calibration of the thermometer.
The least count of a half meter scale is 0.5 cm. This means that the smallest measurement that can be accurately obtained using the scale is 0.5 cm.
least count of scale is 1mm
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
The least count of a half meter rod is 0.5 cm. This means that the rod can be measured in increments of 0.5 cm, allowing for precise measurements.

least count of a micrometer= pitch/no of division on the circular scale

The least count of a physical balance is the smallest measurement that can be read or displayed on the balance scale. It is determined by the precision of the scale and the smallest division marked on the scale or indicated by the scale's display.
The least count of a screw gauge is calculated by dividing the pitch of the screw by the number of divisions on the circular scale. The formula is Least Count = Pitch / Number of divisions on the circular scale.
The least count of a thermometer scale is the smallest temperature difference that can be measured by the scale. It is typically based on the precision of the markings on the scale, which can vary depending on the design and calibration of the thermometer.
Least count is the smallest form of measurement that a specific measuring instrument can accurately measure by. So meter stick uses 1m and 100cm and 1000mm. Thus mm is the least count for a meter stick.
