Differences between Kilometer and Mile
Kilometer vs. Mile[edit]
The kilometer and the mile are both units of length used to measure geographical distances. The kilometer is a unit within the metric system, which is the official system of measurement for most of the world.[1][2] The mile is a unit in the imperial and United States customary systems.[1] A mile is longer than a kilometer; one mile is equal to approximately 1.609 kilometers, and one kilometer is equal to approximately 0.621 miles.[3][4][5]
The International System of Units (SI), the modern form of the metric system, uses the kilometer as a primary unit for terrestrial distance. Its use is widespread globally. The mile is used for road signage and general distance measurement in a few countries, most notably the United States and the United Kingdom. Liberia and Myanmar have also historically used the imperial system.
The origin of the mile dates to Roman times, derived from the Latin mille passus, or "a thousand paces".[5] Its length was later standardized in England in 1593 to be 5,280 feet.[5] The kilometer was introduced in France in 1795 after the French Revolution as part of the new decimal-based metric system.[2] It was defined as one-thousandth of a meter.
Comparison Table[edit]
| Category | Kilometer | Mile |
|---|---|---|
| System of measurement | Metric (SI) | Imperial and U.S. customary |
| Symbol | km | mi |
| Equivalent length | 1,000 meters | 1,760 yards or 5,280 feet |
| Metric equivalent | 1,000 meters | 1,609.344 meters |
| Imperial equivalent | 0.621 miles | 1 mile |
| Origin | 18th-century France[2] | Roman Empire[5] |
| Primary Usage | Worldwide, except for a few countries[1] | United States, United Kingdom[1] |
History and Usage[edit]
The mile's definition evolved from the Roman measurement of 5,000 feet.[5] The English statute mile was established during the reign of Queen Elizabeth I.[5] The statute made the mile equal to eight furlongs, a common agricultural measurement at the time, resulting in the current length of 5,280 feet. Today, the mile remains the standard unit for road distances and speed limits in the United States and the United Kingdom.[1]
The kilometer was conceived by French scientists in the late 18th century as part of a logical, decimal-based system of measurement.[2] This new "metric" system was based on the meter, which was originally defined as one ten-millionth of the distance from the Earth's equator to the North Pole.[2] The system's simplicity, with units based on powers of ten, facilitated its adoption across much of the world for scientific, commercial, and general use.[1][2] Most countries now use kilometers for official measurements of distance.[1]
