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.
Are (a)
An are is a metric land unit equal to 100 m², originally invented during the development of the metric system but now largely overshadowed by the hectare (100 ares). Although rarely used independently in modern measurement, the are survives in real estate transactions in parts of Europe, where small land parcels—such as garden plots or rural homesteads—may be expressed in ares. It remains important historically, as it served as a transitional unit bridging the earliest metric innovations with modern large-scale land measurement practices.
