The least count of a cross staff is typically around 0.5 degrees. This means that it can measure angles with a precision of about half a degree.
for a levelling staff the least count is 0.01in and in m 0.005m
The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale
The least count of a thermometer is the smallest temperature difference that it can measure accurately. Typically, for a standard mercury-in-glass thermometer, the least count is 0.1°C.
Doubling the number of divisions on the circular scale of a spherometer will decrease the least count by half. The least count is inversely proportional to the number of divisions, so as the number of divisions increases, the least count decreases.
The least count of a stopwatch is typically 0.01 seconds, although some models may have a higher or lower least count depending on their specific design and features. The least count refers to the smallest increment of time that can be accurately measured by the stopwatch.
for a levelling staff the least count is 0.01in and in m 0.005m
A Cross Staff and a Quadrant are Instruments that measure Latitude.

No.
The cross staff was used to determine the vessels latitude by measuring the altitude of Polaris or the Sun.

5 mm is the least count of theodolite.
A friend you can count on!
least count for micrometer is 0.01mm0.01 mm
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm
