Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 miles × 20 miles) has an area of 400 sq mi; a rectangle of measuring 10 miles × 40 miles also has an area of 400 sq mi, but is not 20 miles square.
The map shows that the area of the island is about two square kilometres. Topographical map grids are worked out in metres, with the grid lines being 1,000 metres apart. 1:100,000 maps are divided into squares representing 1 km 2, each square on the map being one square centimetre in area and representing 1 km 2 on the surface of the Earth.
The square root appearing above can be eliminated for such applications as ordering locations by distance in a database query. On the other hand, some methods for computing nearest neighbors, such as the vantage-point tree , require that the distance metric obey the triangle inequality , in which case the square root must be retained.

This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes unrecognized but de facto independent countries. The figures in the table ...
A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.

San Francisco is an extreme example: water makes up nearly 80% of its total area of 232 square miles (601 km 2). In many cases an incorporated place is geographically large because its municipal government has merged with the government of the surrounding county.
