The term "micron" is a unit of measurement used to express lengths or distances, particularly in the fields of science, engineering, and manufacturing. It is a unit of length in the metric system and is equal to one millionth of a meter, or 0.000001 meters. The symbol for the micron is "µm," where the Greek letter "mu" (µ) represents "micro," indicating that it is a very small unit of measurement.
Microns are commonly used to measure things at a microscopic level, such as the size of cells, particles, or features on a microchip. It's also used in various industries for precision measurements and quality control, particularly in fields like electronics, optics, and materials science. In some contexts, microns may also be referred to as micrometers.
A "link" is a unit of length that is equivalent to 1/100th of a chain. In the United States customary system of measurement, one link is equal to 7.92 inches or 0.201168 meters. It is primarily used in surveying and land measurement.
Links are often used in conjunction with other surveying units like chains and rods to measure distances on land, especially for large plots or parcels of land. The term "link" is rarely used in everyday conversation or modern applications outside of surveying and related fields. Instead, more common units like feet, yards, or meters are used for measuring length in most contexts.
