   en.wikipedia.org/wiki/Calipers

   Ordinary 150 mm (6 in) digital calipers made of stainless steel have a rated accuracy of 0.02 mm and a resolution of 0.01 mm (0.0005 in). [11] The same technology is used for longer calipers, but accuracy declines to 0.03 mm (0.001 in) for 100–200 mm (4–8 in) and 0.04 mm (0.0015 in) for 200–300 mm (8–12 in) measurements.

   en.wikipedia.org/wiki/Vernier_scale

   Vernier caliper scales; main at top, vernier at bottom. It reads 3.58 ± 0.02 mm by adding 3.00 mm (left red mark) on the fixed main scale to vernier 0.58 mm (right red mark). The main scale reading is that to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales.

4. Micrometer (device) - Wikipedia

   en.wikipedia.org/wiki/Micrometer_(device)

   A standard one-inch micrometer has readout divisions of 0.001 inch and a rated accuracy of ±0.0001 inch [15] ("one tenth", in machinist parlance). Both the measuring instrument and the object being measured should be at room temperature for an accurate measurement; dirt, operator skill issue, and misuse (or abuse) of the instrument are the ...

   The triple prime ‴, as used in watchmaking, represents a ligne (1 ⁄ 12 of a "French" inch, or pouce, about 2.26 millimetres or 0.089 inches). [3] Primes are also used for angles. The prime symbol ′ is used for arcminutes (1 ⁄ 60 of a degree), and the double prime ″ for arcseconds (1 ⁄ 60 of an arcminute). [4]
