Least count uncertainty is one of the sources of experimental error in measurements.The least count is related to the precision of an instrument; an instrument that can measure smaller changes in a value relative to another instrument, has a smaller least countbvalue and so is more precise. Any measurement made by the instrument can be considered repeatable to no less than the resolution of the least count. The least count of an instrument is inversely proportional to the precision of the instrument.
