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.
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.
