Vernier Caliper ( Science and Technology)

Vernier Caliper

A Vernier caliper is measuring scale it is used in Horizontal and Depth place measure.  If a two scale one main scale and second Vernier scale. 

Vernier caliper

One small division on main scale = 1 mm

No. of divisions on Vernier scale = 50

50 Vernier scale divisions = 49 divisions on main 

scale (or 49 mm)

Each division on Vernier scale = (49/50) mm

Difference between one main scale division and one 

Vernier scale division = 1 - (49/50) mm

= (50 - 49)/50

= (1/50) mm

= 0.02 mm

Least Count = 0.02 mm

Least count = 0.02
