The square mile, a unit of area unique to imperial and U.S. customary systems, is often associated with vast expanses of land, particularly in regions like the United States and Canada. Historically used to map territories and cities, the square mile encompasses an area equivalent to 640 acres. One particularly fascinating application of the square mile is in city planning: Manhattan, one of the world’s most densely populated areas, covers about 22.7 square miles yet houses over a million residents!

Another interesting aspect is the “square mile of influence”: cities like London have financial districts, each around one square mile, that wield immense global economic power. These districts, often referred to simply as “The City,” play crucial roles in shaping world markets, showing how a single square mile can be the epicenter of international financial activity.

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.
