What is Square Mile?

The square mile is a unit of area in the imperial and US customary systems, equal to a square with sides of one mile, or exactly 640 acres. In the United States and United Kingdom, it is used for the areas of counties, states, cities, and other large regions. Manhattan Island in New York City covers about 23 square miles, and the City of London is just 1.12 square miles. Population density figures in English-speaking countries are typically given as persons per square mile.

What is Are?

The are is a unit of area equal to 100 square meters, or a square 10 meters on each side. It was introduced as part of the metric system during the French Revolution. While less commonly used today than the hectare (which equals 100 ares), the are still appears in land registration documents and real estate descriptions in some countries. In Japan and parts of Europe, small plots of land may be described in ares. The prefix "hect-" in hectare literally means one hundred ares.
