The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale
The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.
for a levelling staff the least count is 0.01in and in m 0.005m
A prismatic channel is a type of open channel with a trapezoidal cross-section. It has a flat bottom and side slopes that form a trapezium shape. Prismatic channels are commonly used in engineering for water flow and drainage systems.

prismatic surveying and surveying compass.
To use a prismatic compass, first ensure it is set up correctly by adjusting the azimuth ring to align with magnetic north. Then, hold the compass level and sight your target through the prism while reading the azimuth on the compass dial. Ensure you compensate for any declination angle if needed.
Individual Compass Error.
The prismatic compass is a type of compass use for survering a land.
Local attractions such as buildings or metal objects can affect the accuracy of a prismatic compass survey by causing magnetic interference. This interference can lead to errors in compass readings and, consequently, inaccurate survey measurements. To minimize these effects, surveyors should identify and account for local attractions during their surveys, employing techniques such as taking multiple readings and using a declination correction.
advantage it helps u know the direction of your measurement in relation to magnetic bearing disadvantage it is affected by the weather

The points of the compass, like North, East, South, and West, were established based on the Earth's magnetic field. They have been used for navigation for centuries and have become standardized to provide clear and consistent directional references.
