About these units
Hectare (ha)
A hectare is equal to 10,000 m², or 0.01 km², and is the standard unit of land measurement in agriculture, forestry, and land management across most of the world. Unlike the acre, which comes from historical English land systems, the hectare is fully metric and integrates cleanly into scientific practice. Farmers use hectares to measure fields, crop yields, irrigation requirements, and livestock capacity. Foresters rely on hectares for forest inventories, timber production estimates, and biodiversity assessments. Urban planners use hectares when describing zoning, green space, and population density. The hectare is the perfect intermediate scale: large enough for meaningful land plots, and small enough to avoid unwieldy numbers when describing farms or urban districts.
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.
