------------------------------------------------- The "Least Count" of any measuring equipment is the smallest quantity that can be measured accurately using that instrument.Thus Least Count indicates the degree of accuracy of measurement that can be achieved by the measuring instrument. All measuring instruments used in physics have a least count. A meter ruler’s least count is 0.1 centimeter; an electronic scale has a least count of 0.001g‚ although this may vary; a vernier caliper has a least count of 0.02 millimeters
