The mile is an English unit of length of linear measure equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959.

While most countries replaced the mile with the kilometre when switching to the International System of Units, the international mile continues to be used in some countries, such as Liberia, the United Kingdom, the United States, and a number of countries with fewer than one million inhabitants, most of which are UK or US territories, or have close historical ties with the UK or US.

The mile was usually abbreviated m. in the past in the USA but is now written as mi to avoid confusion with the SI metre. However, derived units, such as miles per hour or miles per gallon, continue to be abbreviated as mph and mpg, respectively. In the United Kingdom, road signs still abbreviate mile to m.
