About these units
Square Centimeter (cm²)
A square centimeter is the area of a square 1 cm per side. It is widely used in medicine, biology, and materials science because it provides a practical scale for human-sized and laboratory-sized areas. Dermatologists measure wound sizes in cm², biologists quantify cell culture plates in cm², and materials engineers specify surface treatments, coatings, and cross-sections using this unit. The cm² offers an intuitive middle ground between mm² (too small for many biological phenomena) and m² (too large for typical laboratory work), making it a universal unit in the sciences.
Square Mile (US Survey) (mi² (US))
The US survey square mile is extremely close to the international square mile but is defined using the US survey foot, a slightly different value than the international foot historically used in land surveying. This unit appears in American land deeds, cadastral maps, and federal land management documents. The Public Land Survey System (PLSS), which divided much of the western United States into townships and sections, relied heavily on survey-based square miles. Although the modern US has transitioned to the international foot (as of 2023), historical land descriptions remain legally tied to the survey-based definition, ensuring its continued relevance.
