Micron
A micron (µ) is another name for the micrometer and equals one-millionth of a meter. Although the term “micrometer” is the official scientific unit, “micron” is still widely used in fields like biology, manufacturing, and material science. This tiny unit helps measure fibers, particles, and microscopic structures.
Because microns are so small, they are essential in technologies such as air filtration, semiconductor production, and optical equipment. Converting microns to millimeters or nanometers is easy with a converter, making high-precision work more manageable.
Millimeter
A millimeter (mm) is a small metric unit of length equal to one-thousandth of a meter. It is ideal for precise measurements like product packaging, engineering drawings, and small household objects. Many rulers and calipers include millimeter markings to help measure with accuracy.
Since 10 millimeters = 1 centimeter, converting between nearby metric units is simple. When switching to imperial units—for example, 1 mm ≈ 0.03937 inches—a conversion tool offers quick and accurate results.
