It is commonly used in engineering, manufacturing, and science for measuring small cross-sectional areas, such as wire gauges, material thickness, and precision components. In electrical engineering, conductor cross-sections are often specified in square millimetres. It is one of the most practical small-area metric units in technical applications.
