The square foot is a unit of area commonly used in the United States and some parts of Canada to measure spaces such as real estate, architecture, and interior design. One interesting fact about the square foot is that it originated from the Roman “pes,” or foot, which in ancient times was roughly 11.65 inches but has evolved into the standardized 12-inch foot we know today. The Roman builders’ influence is still evident as the technology advanced, yet the measurement conventions from thousands of years ago persist.

A square foot can tell fascinating stories about the world around you; for example, did you know that the average human adult has around 20 square feet of skin? Or that the Guinness World Record for the largest pizza ever baked covered an astounding 13,580 square feet? These unique perspectives add intriguing dimensions to our understanding of space, showcasing just how versatile and historically rich this seemingly simple unit of measure can be.

The “are” is a unit of area primarily used in land measurement, notably in countries employing the metric system. Introduced in France in 1795, it represents 100 square meters, making it a practical unit for comparing parcels of land. Interestingly, it’s the base unit for hectares, with one hectare equating to 100 ares or 10,000 square meters. While the are has been largely overshadowed by hectares in commercial and agricultural contexts, it remains a vital unit in some regions for surveying smaller plots. The persistence of the “are” in certain legal and cultural settings highlights how historical units can remain relevant despite broader shifts towards newer measurement systems.
