What are three differences and similarities between a Vernier Calipers and a Micrometer? (please leave a good answer)

differences:

The resolution. A micrometer provides smaller resolution compared to calipers. A micrometer can measure down to 0.001mm (micron size), while a caliper can measure down to 0.02 only in general. Resolution is the smallest increment that can be measured.

Range. A micrometer has different ranges. The most used range is 1 inch. However, there are available in 2inch, 3inch, 4inch, 5inch, 6inch, etc. While a caliper has a fairly uniform size.

How They Work. The way mechanical works is by the help of the differential screw mechanism, while the vernier caliper uses vernier scale. The digital micrometers also work differently from the digital calipers.

similarities:

Both are simple to use and easy for measurement.

Both Vernier caliper and micrometer screw gauge might have zero error to some extent. However, the zero error can be calculated and removed.

Both have ability to measure small dimensions

Explanation:

Vernier scale

Mathematical tool

A vernier scale, 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 error. Wikipedia

Purpose: Measuring more precisely than could be done unaided when reading a uniformly divided straight or circular measurement scale

Creator: Pierre Vernier

Year invented: 1631

A micrometer is a measuring instrument that can make extraordinarily precise measurements. Most micrometers are designed to measure within one one-thousandth of an inch! That's a close fit. Exact measurements like this are necessary when even the smallest of space between objects can cause problems or difficulties.

Micrometer

Mathematical tool

A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
