In Chicago, a typical city block is 330 by 660 feet (100 m × 200 m), [2] meaning that 16 east-west blocks or 8 north-south blocks measure one mile, which has been adopted by other US cities. In much of the United States and Canada, the addresses follow a block and lot number system , in which each block of a street is allotted 100 building ...
Each side has taxicab length 2r, so the circumference is 8r. Thus, in taxicab geometry, the value of the analog of the circle constant π , the ratio of circumference to diameter , is equal to 4. A closed ball (or closed disk in the 2-dimensional case) is a filled-in sphere, the set of points at distance less than or equal to the radius from a ...
The rest of the city, including the eastern part of downtown, is laid out primarily on a grid oriented to the cardinal directions. In this larger grid, from east to west, there are generally 16 city blocks per mile, except between Zuni Street and Lowell Boulevard in west Denver. From north to south, there are typically eight blocks per mile ...
In most US cities, a city block is between 1 ⁄ 16 and 1 ⁄ 8 mi (100 and 200 m). In Manhattan, the measurement "block" usually refers to a north–south block, which is 1 ⁄ 20 mi (80 m). Sometimes people living in places (like Manhattan) with a regularly spaced street grid will speak of long blocks and short blocks.

In the United States, the term statute mile formally refers to the survey mile, [3] but for most purposes, the difference of less than 1 ⁄ 8 inch (3.2 mm) between the survey mile and the international mile (1609.344 metres exactly) is insignificant—one international mile is 0.999 998 US survey miles—so statute mile can be used
It is a defined area, varying in size from part of a city block to large areas of rural land. Each of these borders another to form a network covering the whole country including inlets and coasts, and extending out to the 200 mile economic zone. Meshblocks are added together to "build up" larger geographic areas such as area units and urban areas.
