In the science of measurement, the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale. [1] The least count is related to the precision of an instrument; an instrument that can measure smaller changes in a value relative to another instrument, has a smaller "least ...
The standard for a caliper is usually a constant of 0.02 Vernier caliper scale with the normal 0.02 vernier constant, showing measurement of object at 19.44 mm to two decimal places The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object.
A micrometer, sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw widely used for accurate measurement of components [1] in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.

A single tool might be referred to as a caliper or as calipers — a plural only (plurale tantum) form, like scissors or glasses. Colloquially, the phrase "pair of verniers" or just "vernier" might refer to a vernier caliper.
