The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10−6 metre (SI standard prefix "micro-" = 10−6); that is, one million...

A micrometer, sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw for accurate measurement of the size of components. [1] It widely used in mechanical engineering , machining , metrology as well as most mechanical trades, along with other dimensional instruments such as dial , vernier , and digital ...

A micrometer also called a micron, is a metric unit of measure for a length equal to 0.001 mm, or about 0.000039 inches. Its symbol is μm. The micrometer is commonly employed to measure the thickness or diameter of microscopic objects, such as microorganisms and colloidal particles.

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.

A micrometer is another useful device for magnifying small measurements. In micrometer, the accurate screw and nut are used for measurement. The micrometers having good accuracy (about 0.01 mm), hence is used for most engineering precision work. Principle of micrometer. Micrometers works on the principle of screw and nut.
