What is Micrometer?
A micrometer is an instrument used for making precise linear measurements of dimensions such as diameter, thickness, and lengths of solid bodies. It is made of a C-shaped frame with a movable jaw operated by an integral screw. The fineness of the measurement depends on the lead of the screw while the accuracy of the measurement depends on the accuracy of the screw-nut combination.
What is the principle of a micrometer?
The basic operating principle of a micrometer are as follows: The amount of rotation of an accurately made screw can be directly and precisely correlated to a certain amount of axial movement (and vice versa), through the constant known as the screw’s lead. A screw’s lead is the distance it moves forward axially with one complete turn (360°).

What is the symbol for micron?
The term which is micron is also the symbol denoted by μ were officially said to be accepted for use in isolation to denote the micrometre in 1879 but was officially revoked by the International System of Units that is the SI in 1967. This generally became necessary because of the reason that the older usage was incompatible with the official adoption which was of the unit prefix micro- which is denoted by μ during the creation of the SI in 1960.
Overview
The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equalling 1×10 metre (SI standard prefix "micro-" = 10 ); that is, one millionth of a metre (or one thousandth of a millimetre, 0.001 mm, or about 0.00004 inch).
Examples
Between 1 μm and 10 μm:
• 1–10 μm – length of a typical bacterium
• 10 μm – Size of fungal hyphae
• 5 μm – length of a typical human spermatozoon's head
SI standardization
The term micron and the symbol μ were officially accepted for use in isolation to denote the micrometre in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted μ, during the creation of the SI in 1960.
In the SI, the systematic name micrometre became the official name of the unit, and μm becam…
Symbol
The official symbol for the SI prefix micro- is a Greek lowercase mu. In Unicode, there is also a micro sign with the code point U+00B5 (µ), distinct from the code point U+03BC (μ) of the Greek letter lowercase mu. According to the Unicode Consortium, the Greek letter character is preferred, but implementations must recognize the micro sign as well. Most fonts use the same glyph for the two characters.
