定义
A mile (symbol: mi) is an Imperial and U.S. customary unit of length equal to exactly 5 280 feet, 1 760 yards, or 1 609.344 meters.

起源
源于拉丁文 里程碑 (“thousand paces”), the mile was standardized in England in 1593 as 8 furlongs (5 280 ft). Variants like the Roman mile (5 000 ft) and the nautical mile (1 852 m) persist in specialized contexts.

现代使用
Miles remain the standard on highways and road signs in the U.S., U.K., Myanmar, and Liberia. They’re also used for aviation (statute vs. nautical miles) and in some sporting events.

• 1793: One ten-millionth of the Earth’s quadrant from Equator to North Pole

• 1889: Defined by a platinum–iridium prototype bar at 0 °C

• 1960: Recast in terms of krypton-86 emission wavelengths

• 1983-2019: Anchored to the fixed speed of light

现代使用
Meters dominate science, engineering, construction, and everyday measurements worldwide. Though the U.S. often uses customary units, meters underpin its scientific and trade standards.
