About these units
Square Rod (US Survey) (rod² (US))
The US survey square rod is defined using the survey foot and differs negligibly from the international square rod. This distinction matters in legal contexts, especially when interpreting older property descriptions dating back to the 19th-century PLSS-era surveys. The unit persists primarily in legal documents and rural land records, ensuring that historical boundaries remain consistent even as measurement standards evolve.
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.
