Mile Conversion Calculator — Miles to km, Feet, Meters
Convert any distance in miles to kilometers, meters, feet, yards, centimeters and nautical miles. All conversions use the exact international definition: 1 mile = 1609.344 meters.

这个计算器是如何工作的？
1 mile = 1,609.344 m = 1.609344 km = 5,280 ft = 1,760 yd (all exact definitions). Multiply miles by 1.609344 for km, by 5,280 for feet, or by 1,760 for yards. For nautical miles divide by 1.1508 (since 1 nmi = 1,852 m).

How this is calculated
The statute mile is defined internationally as exactly 1609.344 meters, a definition fixed in 1959 by agreement among English-speaking countries. Because it is an exact definition, all mile-based conversions are free of rounding drift: 1 mile = 5,280 feet and 1 mile = 1,760 yards are also exact (since 1 foot = 0.3048 m and 1 yard = 0.9144 m are both defined exactly).
To convert to kilometers, multiply by 1.609344. To feet, multiply by 5,280. To meters, multiply by 1,609.344. To yards, multiply by 1,760. The nautical mile is a separate unit defined as exactly 1,852 meters, used in aviation and maritime navigation — 1 statute mile ≈ 0.86898 nautical miles.
For the reverse conversion (e.g. km to miles), divide by the factor: 1 km = 1 ÷ 1.609344 ≈ 0.62137 miles. A useful rough rule is that 8 km ≈ 5 miles (since 8 ÷ 5 = 1.6, close to the exact 1.609344 factor).
常见问题
1 mile = exactly 1.609344 kilometers. For quick mental math, multiply miles by 1.6 (or use the 5/8 ratio: 5 miles ≈ 8 km). To convert km to miles, multiply by 0.621371.
There are exactly 5,280 feet in a mile. This comes from the historical definition: 1 mile = 8 furlongs, 1 furlong = 10 chains, 1 chain = 66 feet, so 8 × 10 × 66 = 5,280. It is also exactly 1,760 yards.
A statute (land) mile = 1,609.344 m. A nautical mile = 1,852 m (1 minute of arc along the Earth's meridian). They are different units: 1 nautical mile ≈ 1.1508 statute miles. This calculator uses statute miles.
