The micrometre (or micrometer in US spelling; symbol: μm) is a unit of length in the International System of Units (SI) equalling 10−6 metre (SI standard prefix "micro-" = 10−6); that is, one millionth of a metre (or one thousandth of a millimetre, 0.001 mm, or about 0.000 04 inch). It is also known as the micron. [1]
It is equal to one millionth of a meter or 0.000001 meters. The symbol for micrometer is μm, derived from the Greek letter "mu" (μ) which represents micro, meaning one millionth. The micrometer is commonly used in scientific and engineering fields where precise measurements are required.
micrometre, metric unit of measure for length equal to 0.001 mm, or about 0.000039 inch. Its symbol is μ m. The micrometre is commonly employed to measure the thickness or diameter of microscopic objects, such as microorganisms and colloidal particles.
A strain is usually expressed in μm/m (micrometer per meter), also known as microstrain, which has the symbol µε. You may also see “mV/V,” which refers to the output in millivolts per volt of excitation.

What is a Micron? A micron, pronounced mahy-kron comes from the Greek word mīkrón, meaning a little. A micron or micrometer/micrometer or µm is a measurement used in sciences, industry, and English-speaking countries. Why use Micron as a Measurement?
