About Feet and Miles
Feet (ft): An ancient unit found in virtually every culture, historically based on the human foot; defined as exactly 0.3048 meters by the 1959 International Yard and Pound Agreement. Common uses: Human height in the United States, building heights, room dimensions, aviation altitudes (universally, even in metric countries), and yards/football fields in American sports.
Miles (mi): From the Roman mille passus, 'a thousand paces' of a Roman legionary; the modern statute mile is 1,609.344 meters exactly by the 1959 International Yard and Pound Agreement. Common uses: US road distances, running and cycling distances in the US and UK, marine and aviation navigation (as nautical miles, a slightly different unit at 1,852 m), and altitude in some specialized contexts.
How the conversion works
Length conversions use the SI definition: 1 inch is exactly 0.0254 meters and 1 mile is exactly 1,609.344 meters. The factor above is the exact ratio between foot and mile.
The exact relationship is miles = feet × 1.89393939e-4, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between feet and miles comes up wherever length measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
