The information that we collect from the measurement of least count is generally an error that can be positive or negative, based on the position of zero on the Vernier scale and main scale. Least count can also be calculated by taking the difference of one main scale division and one Vernier scale division. Hence, the least count for Vernier Callipers is 0.1mm. Least count = $\dfrac$ = This is the least count for Vernier Callipers. Least count of a Vernier scale is calculated using the following formula, In case of a Vernier caliper, the Vernier scale has divisions of size a bit less than that of the smallest division on the main scale.
Least count is defined as the smallest value a measuring device can measure and is also known as Vernier constant.
