verniers
Fractional reading aids
Verniers are small sliding scales used to obtain fine measurements on instruments like calipers and micrometers.
The vernier scale sits alongside the main scale, allowing readings between the smallest marked divisions—typically to a tenth or hundredth of a unit.
The machinist checked the verniers to get an exact measurement.
Named for French mathematician Pierre Vernier.
