History

Inch (in)

The inch, abbreviated as in, is a length unit in the imperial and US customary systems. Its history reaches back to ancient civilizations, including the Romans, Egyptians, and Anglo-Saxons. Originally, the inch was determined by the width of a human thumb, but it was eventually set as 1/12 of a foot. Since 1959, the inch has been officially defined as exactly 2.54 centimeters due to an international agreement. Inches are still widely used in the United States, Canada, and the UK, especially for construction, manufacturing, and personal measurements. Even with the global shift to metric units, the inch remains important in certain fields such as technical drawings, screen dimensions, and household tools.

Mile (mi)

The mile, symbol mi, is an imperial unit of length traditionally defined as 5,280 feet or 1,609.344 meters. Its origin dates back to Roman times, from mille passus, meaning a thousand paces. The mile became standardized in England in the 16th century and is widely used in the United States, the UK, and some Commonwealth countries. Miles are common in road distances, running races, and nautical contexts (converted into nautical miles at sea). Despite global metric adoption, the mile’s enduring presence demonstrates its historical and practical significance in transportation and navigation.
