Answers:Basically, the parameter deciding how appropriate an instrument is before being used in a particular situation is its LEAST COUNT. The usual least count of a vernier calipers is usually 0.1mm, so when we are dealing with situations involving measurements not more minute than 0.1 mm we can safely avail of its use. The least count of a GENERAL vernier caliper can be easily determined in the following manner. A vernier caliper consists of a fixed main scale and a sliding vernier scale which, as the name suggests, slides on the main scale. The value of one division on a main scale is 1mm and on the vernier scale there are ten divisions which are equal to nine divisions of a main scale. So the value of each vernier scale mark is 0.9mm(9X1/10). The formula for calculation of the least count of a vernier scale is : Value of one M.S. division - value of one V.S. division, which comes out to be 0.1 mm, hence my statement earlier. Along with this V.C. is also used to measure the internal and external diameters of cylinders, bottles etc. There are instruments which are even more accurate than V.C. such as screw gauge which has a least count of 0.01mm.
