About these units
Square Micrometer (µm²)
A square micrometer, also called a square micron, equals 10⁻¹² square meters. It is a fundamental unit in microbiology, nanotechnology, semiconductor physics, and materials characterization. Cells, organelles, thin films, and laser spot sizes are frequently measured in µm². In semiconductor fabrication, transistor gates, nanoscale features, and photolithographic patterns often have areas measured at this scale. At such dimensions, quantum effects, crystal lattice structures, and electron mobility become important, making µm² not just a geometric unit but a bridge to fundamental physical behavior at microscopic scales.
Square Inch (in²)
A square inch represents the area of a one-inch by one-inch square. It is indispensable in engineering, manufacturing, machine design, and consumer product specifications. Mechanical components, gasket areas, electronic device screens, and pipe cross-sections are often measured in square inches. Because imperial units are deeply rooted in American manufacturing, the square inch enables precise communication among engineers and technicians. The unit remains important in pressure measurement as well—psi (pounds per square inch) combines force and area into one of the most widely recognized engineering units worldwide.
