Vernier scale

Quality 0.00 · 0 views · Updated 16 days ago

A vernier scale (/ˈvɜːrniːər/ VUR-nee-ər), named after Pierre Vernier, is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation, which increases resolution and reduces measurement uncertainty by using vernier acuity. It may be found on many types of instrument measuring length or measuring angles, but in particular on a vernier caliper, which measures lengths of human-scale objects (including internal and external diameters).
