The vernier scale is divided into 12 spaces on each side of the 0 line, which occupy the same space as 23\u00b0 the protractor dial. By simple calculation, it is easy prove that one vernier space is 5 , or less than two graduations on the main scale. If zero on the vernier scale coincides with a line on the main scale, the reading will be degrees only. However, if any other line on the venier scale coincides with a line on the main scale, the number of vernier graduations beyond the zero should be multiplied by 5 and added to the number of full degrees indicated on the protractor dial.
