Since the least count of the Vernier caliper is 0.001 cm, it can be said that when measuring with the help this Vernier caliper, you can get an accuracy of 0.001 cm. The Vernier scale division is obtained by counting number of division in it. The least count as the name suggests is the finest measurement you can take with the help of that Vernier calipers. Least Count of Vernier calipers= 0.001 cm The Vernier caliper least counts formula is calculated by dividing the smallest reading of the main scale with the total number of divisions of the vernier. Least Count of Vernier calipers = 0.01/ 10 cm Use a magnifying glass if necessary.įor most Vernier calipers least count of main scale = 0.01 cm and number of divisions on Vernier scale = 10 divisions. Count the number of divisions on the Vernier scale.
Number of divisions on Vernier scale: In most Vernier calipers, the Vernier scale has 10 divisions. Calculate the least count and only then place the object between the two jaws. In screw gauge, let l be the distance between two adjacent divisions on the linear scale. L.C Value of smaller division on MS/Total Number of division on VS. The least count of the Vernier calipers is given by LC 1 MSD - 1 VSD 0.125 - 0.1 0.025 cm. For example, if there are 10 divisions in one centimeter of the main scale its least count = 1/10 = 0.1 cm. The least count of a Vernier calliper is known as the Vernier constant. least count of metric vernier caliper ( english )to learn about (iti) fitter basic trainingdirect click this link or copy paste to url. The least count of vernier calipers can also be calculated as following. Divide 1 cm into that much number of divisions the value obtained is the least count of the main scale in cm. To get the least count of the main scale, count the number of divisions on the main scale in one cm of it.
Least count of the main scale: The main scale is calibrated in millimeters. Least count =Least count of main scale / Number of divisions on Vernier scale. The Least Count (LC) of Vernier scale is given as The pitch p of the screw gauge is the distance travelled on the linear scale when it makes one complete rotation. It is measured by dividing the least count of the main scale by the total number of divisions on the Vernier scale. The least count of the Vernier calipers is given by LC 1 MSD - 1 VSD 0.125 - 0.1 0.025 cm. The least count as the name suggests is the finest measurement you can take with the help of that Vernier calipers.
