The Formula to find Least count of vernier caliper is

L.C. = (Largest division on Main Scale ) / (Total number of divisions on Vernier Scale)

L.C. = (Smallest division on Main Scale ) / (Total number of divisions on Vernier Scale)

L.C. = (Total number of divisions on Vernier Scale) / (Smallest division on Main Scale)

L.C. = (Smallest division on Main Scale + Largest division on Main scale ) / (Total number of divisions on Vernier Scale)
