Quick Reference Conversion Table

Step-by-Step Conversion Instructions

Example: Convert 15,840 feet to miles

1. Divide the number of feet by 5,280:
   [ 15,840 \div 5,280 = 3 ]
   Therefore, 15,840 feet equals 3 miles.

Practical Examples

Example 1: Measuring a Road Trip Distance

A road is 26,400 feet long. To convert this distance to miles:

1. Divide the distance in feet by 5,280:
   [ 26,400 \div 5,280 = 5 ]
   The road is 5 miles long.

Example 2: Estimating a Marathon in Feet to Miles

A marathon is approximately 138,435 feet in length. Converting this to miles:

1. Divide the distance in feet by 5,280:
   [ 138,435 \div 5,280 = 26.2 ]
   Thus, a marathon is approximately 26.2 miles long.
