What is a Feet to Miles Converter?

A Feet to Miles Converter is a tool used to convert measurements of length or distance from feet (ft) to miles (mi) and vice versa. This conversion is commonly used in navigation, travel, surveying, and everyday situations where distances are expressed in either unit.

Understanding this conversion is essential for contexts like road travel in countries using imperial units, aviation, and maritime navigation (though nautical miles are different). It also helps in comprehending geographical distances and land measurements.

Feet to Miles Conversion Formulas

The conversion is based on the standard definition of a mile:

  • Feet to Miles: 
    Miles = Feet / 5280
  • Miles to Feet: 
    Feet = Miles × 5280

Where:

  • ft stands for foot/feet
  • mi stands for mile(s)

How to Convert Feet to Miles: Example

Let's say you have a distance of 13,200 feet.

  1. Identify the value in feet: 13,200 ft
  2. Apply the conversion formula (feet to miles): Miles = 13,200 / 5280
  3. Calculate: Miles = 2.5 mi

So, 13,200 feet is equal to 2.5 miles.

Conversely, if you want to convert 3 miles to feet:

  1. Identify the value in miles: 3 mi
  2. Apply the conversion formula (miles to feet): Feet = 3 × 5280
  3. Calculate: Feet = 15,840 ft

So, 3 miles is equal to 15,840 feet.

Common Applications

This conversion is frequently used in:

  • Road Travel: Calculating distances for driving directions and road signs in the US and UK.
  • Aviation: Pilots often work with distances in statute miles for visibility and other measurements.
  • Surveying: Land surveyors use feet and miles for measuring property boundaries and large tracts of land.
  • Sports: Running and cycling events often have distances measured in miles.
  • Mapping and GIS: Converting between units for geographical data representation.
