A vernier caliper outputs measurement readings in centimetres (cm) and it is precise up to 2 decimal places (E.g. 1.23 cm).Note: The measurement-reading technique described in this post will be similar for vernier calipers which output measurement readings in inches.Measurement Reading Technique For Vernier CaliperIn order to read the measurement readings from vernier caliper properly, you need to remember two things

before we start. For example, if a vernier caliper output a measurement reading of 2.13 cm, this means that:The main scale contributes the main number(s) and one decimal place to the reading (E.g. 2.1 cm, whereby 2 is the main number and 0.1 is the one decimal place number)The vernier scale contributes the second decimal place to the reading (E.g. 0.03 cm)Let's examine the image of the vernier caliper readings above. We will just use a two steps method to get the measurement reading from this:To obtain the main scale reading: Look at the image above, 2.1 cm is to the immediate left of the zero on the vernier scale. Hence, the main scale reading is 2.1 cmTo obtain the vernier scale reading: Look at the image above and look closely for an alignment of the scale lines of the main scale and vernier scale. In the image above, the aligned line correspond to 3. Hence, the vernier scale reading is 0.03 cm.In order to obtain the final measurement reading, we will add the main scale reading and vernier scale reading together. This will give 2.1 cm + 0.03 cm = 2.13 cm.Let's go through another example to ensure th

scale. It is a scale that indicates where the measurement lies in between two of the marks on the main scale. Verniers https://en.wikipedia.org/wiki/Vernier_scale are common on sextants used in navigation, scientific instruments used to conduct experiments, machinists' measuring tools (all sorts, but especially calipers and micrometers) used to work materials to 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 when fully closed) the vernier caliper 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 vernier caliper reading 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. In some languages, the Vernier scale is called a nonius. It was also commonly calle
