to conduct experiments, machinists' measuring tools (all sorts, but especially calipers and micrometers) used to work materials to vernier caliper least count fine tolerances, and on theodolites used in surveying. A close-up of a caliper's measurement scales. Assuming the caliper has no "zero error" (that is, it registers 0.00 mm vernier caliper definition when fully closed) the image shows a reading of 3.58mm ± 0.02mm. This is found by adding 3.00mm (left red mark) read off from the fixed main (upper) scale to 0.58mm (right red mark) obtained from the sliding vernier (lower) scale. The main scale reading is determined by the rightmost tick on the main scale that is to

the left of the zero tick on the vernier scale. The vernier reading is found by locating the closest aligned lines between the two scales. The 0.02mm inscription indicates the caliper's precision and is just the width that corresponds to the smallest interval on the vernier scale.

Calipers without a vernier scale originated in ancient China as early as the Qin dynasty (9 AD).[1][2] The secondary scale, which contributed extra precision, was invented in 1631 by French mathematician Pierre Vernier (1580–1637). Its use was described in detail in English in Navigatio Britannica (1750) by mathematician and historian John Barrow.[3] While calipers are the most typical use of Vernier scales today, they were originally developed for angle-measuring instruments such as astronomical quadrants.

100 cm One meter = 1000 mm Kilogram Kilogram is the unit of mass in S.I. System. "Kilogram is defined as the mass of a platinum cylinder placed in the International Bureau of Weight and Measures in Paris." One kilogram = 1000gram Second Second is the unit of time in S.I. System. A second is defined in terms of the time period of Cs-133 atoms. i.e." one second is equal to 9,192,631,770 periods of vibrations of Cs-133 atoms." 60 seconds = one minute 3600 seconds = one hour Least Count Minimum measurement that can be made by a measuring device is known as " LEAST COUNT'. Least count (vernier callipers) = minimum measurement on main scale / total number of divisions on vernier scale . Least count (screw gauge) = minimum measurement on main scale / total number of divisions on circular scale Smaller is the magnitude of least count of a measuring instrument, more precise the measuring instrument is. A measuring instrument can not measure any thing whose dimensions are less than the magnitude of least count. Least Count of Vernier Callipers = 0.01 cm Least Count of Micrometer Screw gauge = 0.001 cm Zero Error It is a defect in a measuring device (Vernier Callipers & Screw Gauge). When jaws of a Vernier Callipers or Screw Gauge are closed, zero of main scale must coincides with the zero of vernier scale or circular scale in case of screw gauge. If they do not coincide then it is said that a zero error is present in the instrument. Types Of Zero Error Zero error may be positive or negative. A positive zero error in the instrument shows a larger measurement than the actual measurement. In order to get exact measurement, positive zero error is subtracted from the total reading. . A negative zero error in the instrument shows a smaller measurement than the actual measurement. In order to get exact measurement, negative zero error is added to the total reading. Pitch "Perpendicular distance between two consecutive threads of the screw gauge or spherometer is called PITCH." Pitch = Distance traveled on main scale / total number of rotations Error An error is defined as "The difference between the measured value and actual value."
