the least count of half meter rod is 25
In case for micrometer, principle of pitch is used. Least count could be even micro meter But in vernier caliper, difference of main scale division and vernier scale division is the principle Least count could be 0.02 mm
for a levelling staff the least count is 0.01in and in m 0.005m
the least count of travelling microscope = 0.001 cm
The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.

micro meter least count in British system
.02mm
Generally least count of micrometer varies instrument to instrument.. But common micrometers which are used in institute level laboratories have least count of 0.0001mm
yes a metric ruler and a meter ruler is the same
Define the measurement
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.
a meter ruler
a metric ruler, meter-stick, centimeter ruler, and inch ruler are all used to measure length or distance
