The square micrometre, symbolized as µm², is a metric unit of surface area equal to 10⁻¹² square metres or one millionth of a square millimetre. Frequently termed a square micron, it provides a convenient scale for measuring microscopic features like biological cells, semiconductor structures, and material grain boundaries. Its definition is directly tied to the SI metre defined by the General Conference on Weights and Measures.
