![]() This extra fraction can then be calculated as 5*msd-5*vsd or 5(L.C.) or more generally V.C. ![]() The required extra fraction (red rectangle) then is the difference between five main scale divisions (from 2.5 cm to 2.0 cm, sum of the red and orange rectangles = 5 msd) and five vernier divisions (from 2.5 cm of main scale to 0 of the vernier, blue rectangle = 5 vsd. So the distance between the ends of the object plus the length of five divisions of vernier is 2.5 cm. Distance from the other end of the object (at zero of vernier) to the coincidence point is equal to five division lengths of the vernier. It is the fifth vernier division in the figure.ĭistance from one end of the object (at zero of main scale) to the coincidence point is 2.5 cm. Vernier coincidence is the division of vernier which coincides with one of the divisions of the main scale. Main scale reading is the reading just to the left of the vernier zero. In the Animation each main scale division is assumed to be 1 mm. Convince yourself that two scales of unequal division lengths can be used together to make measurements with greater accuracy. Animation illustrates the principle of Vernier calipers.Ī nice tool where measurements less than that of a division of one scale are measured using two scales of different division lengths.
