About these units
Square Foot (ft²)
A square foot is the area of a square one foot on each side. It is widely used in the United States, the UK (historically), Canada (in real estate), and other regions where imperial units remain culturally influential. Square feet dominate property listings, architectural blueprints, and interior design specifications in the US. The measurement provides an intuitive scale for rooms and buildings, fitting well with common human-scaled dimensions. Although metrication has reduced its use worldwide, the square foot remains deeply embedded in construction codes, real estate markets, and consumer expectations in countries that continue to rely on imperial or hybrid systems. Its survival highlights the cultural persistence of traditional measurement systems despite global standardization.
Square Decimeter (dm²)
A square decimeter equals 100 square centimeters or 0.01 square meters. It is used in educational contexts, interior design, textiles, and packaging. Students often learn area concepts using dm² because it bridges the intuitive size of the square meter with the more granular cm². In design fields, dm² helps specify tile surfaces, patterns, laminates, and coverings. Industrial packaging may express surface areas (e.g., of labels or film wrapping) in dm² for regulatory or cost-calculation purposes. It offers a comfortable intermediate scale for everyday applications.
