Miles² to Decimeters² Conversion

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.
