United States customary units are a system of measurements commonly used in the United States. The U.S. customary system developed from English units which were in use in the British Empire before American independence. Consequently most U.S. units are virtually identical to the British imperial units. However, the British system was overhauled in 1824, changing the definitions of some units used there, so several differences exist between the two systems.
The majority of U.S. customary units were redefined in terms of the meter and the kilogram with the Mendenhall Order of 1893, and in practice, for many years before. These definitions were refined by the international yard and pound agreement of 1959. The U.S. primarily uses customary units in its commercial activities, while science, medicine, government, and many sectors of industry use metric units. The International System of Units (SI), the modern form of the metric system, is preferred for many uses by the National Institute of Standards and Technology (NIST).
The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement; however some Imperial units are still used in the United Kingdom and Canada.
The Royal Mile is the name given to a succession of streets forming the main thoroughfare of the Old Town of the city of Edinburgh in Scotland. The name was first used in W M Gilbert's Edinburgh in the Nineteenth Century (1901), and was further popularised as the title of a guidebook, published in 1920.
A rail yard, or railroad yard, is a complex series of railroad tracks for storing, sorting, or loading/unloading, railroad cars and/or locomotives. Railroad yards have many tracks in parallel for keeping rolling stock stored off the mainline, so that they do not obstruct the flow of traffic. Railroad cars are moved around by specially designed yard switchers, a type of locomotive. Cars in a railroad yard may be sorted by numerous categories, including railroad company, loaded or unloaded, destination, car type, or whether they need repairs. Railroad yards are normally built where there is a need to store cars while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations.:46
Many railway yards are located at strategic points on a main line. Main line yards are often composed of an Up yard and a Down yard, linked to the associated railroad direction. There are different types of yards, and different parts within a yard, depending on how they are built.

The Tennessee Volunteers football team (variously called "Tennessee", "Vols", or "UT") represents the University of Tennessee, Knoxville (UT) in the sport of American football. The Volunteers compete in the Football Bowl Subdivision (FBS) of the National Collegiate Athletics Association (NCAA) and the Eastern Division of the Southeastern Conference (SEC).
The run and shoot offense is an offensive system for American football which emphasizes receiver motion and on-the-fly adjustments of receivers' routes in response to different defenses. It was conceived by former Middletown, Ohio, High School football coach Glenn "Tiger" Ellison and refined and popularized by former Portland State Offensive Coordinator Darell "Mouse" Davis.
The Run & Shoot system uses a formation consisting of one running back and between two and four wide receivers. This system makes extensive use of receiver motion (having a receiver suddenly change position by running left or right, parallel to the line of scrimmage, just before the ball is snapped), both to create advantageous mismatches with the opposing defensive players and to help reveal what coverage the defense is using.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain (//), is a sovereign state located off the north-western coast of continental Europe. The country includes the island of Great Britain (a term sometimes loosely applied to the whole state), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another state: the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea in the east, the English Channel in the south and the Irish Sea in the west.
The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. The largest of these territories are Puerto Rico and the American Virgin Islands which are an official part of the United States. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the U.S. mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
