Meter sticks and rulers are engraved with lines which are 1 mm apart. Using them we can try to estimatelengths to 0.1 mm but in practice it is very difficult to achieve an accuracy greater than 0.5 mm becausethat is one-half the least count of the scale. To obtain greater accuracy we need an instrument which willsubdivide the millimeter.
