Convert miles to feet

英里

定义
A mile (mi) is a traditional length unit used in both the Imperial and U.S. customary systems. One statute mile equals exactly 5 280 feet, 1 760 yards, or 1 609.344 meters.

Origins & Evolution
The word “mile” comes from the Latin 里程碑, meaning “thousand paces.” In 1593 England formalized the statute mile at 8 furlongs (5 280 ft) to align with agricultural measures. Before that, various “mile” lengths existed—such as the Roman mile of 5 000 ft. Today, specialized forms like the nautical mile (1 852 m) coexist alongside the standard land mile.

Where It’s Used
Miles are still the norm for road distances and speed limits in the U.S., U.K., Myanmar, and Liberia. Pilots use statute and nautical miles in aviation, and the mile appears in running races and certain sports traditions.

脚

定义
A foot (ft) is a length unit in the Imperial and U.S. customary systems, officially fixed at 0.3048 meters since 1959. It divides into 12 inches and one-third of a yard.

Origins & Evolution
Historically, “foot” measures varied across cultures (Greek, Roman, English, Chinese), often based on human anatomy. To eliminate these inconsistencies, an international agreement in 1959 standardized the foot at exactly 0.3048 m.

Where It’s Used
Feet remain the primary everyday measure in the U.S., Canada, and the U.K. You’ll find them used for personal heights, room dimensions, sports fields, and aviation altitudes.
