2. Vernier scale - Wikipedia

   en.wikipedia.org/wiki/Vernier_scale

   The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.

3. Vernier acuity - Wikipedia

   The calipers in the diagram show a primary reading on the metric scale of about 2.475 cm (2.4 cm read from the main scale plus about 0.075 cm from the vernier scale). Calipers often have a "zero point error": meaning that the calipers do not read 0.000 cm when the jaws are closed.

5. Philadelphia rod - Wikipedia

6. Pierre Vernier - Wikipedia

   en.wikipedia.org/wiki/Pierre_Vernier

   The main scale reading is the rightmost graduation that is to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales. The 0.02 mm engraving indicates the caliper's accuracy and is the "Vernier constant" for this scale. He was born in Ornans, France, in 1580. He was ...
