A vernier scale (/ v ə r ˈ n iː ˈ ə r / ver-NEE-er), 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, thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation ...

Vernier acuity (from the term "vernier scale", named after astronomer Pierre Vernier) is a type of visual acuity – more precisely of hyperacuity – that measures the ability to discern a disalignment among two line segments or gratings. A subject's vernier (IPA: / ˈ v ɜːr n ɪər /) acuity is the smallest visible offset between the ...

The precision-diameter gages consist of a narrow metal ribbon bearing special graduations vernier scale. The vernier scale allows the user more accurately measure diameter. The tapes are checked over master gauges at 0.001 in (0.025 mm) accuracy for standard tapes up to 144 inches (3,658 mm). [3]

Gone are the days of the sad mocktail — the cranberry cocktail topped with a bit of seltzer or a blend of every juice behind the bar. A growing number of bartenders are paying just as much ...
The left height gauge has the vernier scale, while the right one is an electronic height gauge with a digital readout. A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on.
