About the miles to feet converter

To convert miles to feet, multiply by 5,280; to convert back, multiply by 0.0001893939. For example, 1 mi is about 5,280 ft. Displayed factors and results may be rounded.

A route listed in miles may need a metric distance for a map, training log or reimbursement form. This converter uses the international land mile. Nautical miles describe a different distance and need their own conversion rather than a change in rounding.

International definition of mile: 1 mi = 5,280 ft = 1,609.344 m. These values are exact.

Both units are defined exactly. Calculations use 50 significant digits and round only for display.

How many feet are in a mile?

A mile is exactly 5,280 feet, so multiply miles by 5,280: feet = miles × 5,280. A quarter mile is 1,320 ft, half a mile is 2,640 ft and 5 miles is 26,400 ft. This is the statute mile on US and UK road signs; a nautical mile is longer.

Where 5,280 comes from

The mile is 8 furlongs of 660 feet, and 8 × 660 = 5,280. The same mile is 1,760 yards of 3 feet, or 63,360 inches.

The 1959 international agreement fixed the foot at exactly 0.3048 m, which makes the mile exactly 1,609.344 m (NIST Handbook 44, Appendix C).

The feet are exact, because 5,280 is a whole number: every tenth of a mile is 528 ft.

Worked examples

  • Quarter-mile drag strip: 0.25 × 5,280 = 1,320 ft.
  • Marathon: 26.2 miles × 5,280 = 138,336 ft.
  • Four laps of a 400 m track: 1,600 m falls 9.344 m, about 31 ft, short of a full mile.
  • Trail grade: a trail that climbs 1,000 ft in 2 miles rises 1,000 ft over 10,560 ft, a 9.5% grade. Put both lengths in feet before dividing, or use the slope calculator.

Miles plus feet

Convert the miles and add the leftover feet: 1 mile 500 ft is 5,280 + 500 = 5,780 ft.

A decimal is a fraction of a mile, not a foot count. 1.5 miles is 7,920 ft, which is 1 mile 2,640 ft, not 1 mile 500 ft.

Common mistakes

  • Dividing by 5,280. That goes from feet to miles. The foot figure is always the larger number.
  • Using the mile for an area. A square mile is 5,280 × 5,280 = 27,878,400 sq ft, which is 640 acres. The area converter handles land areas.
  • Using a nautical mile. Sea and air charts use the nautical mile of 1,852 m, about 6,076 ft, so 10 nautical miles is about 60,761 ft, not 52,800.

The feet to miles converter goes the other way. For metric distances use miles to km or feet to meters, and the length converter covers yards, inches and nautical miles.

Questions

How many feet are in one mile?

1 mi is about 5,280 ft. International definition of mile: 1 mi = 5,280 ft = 1,609.344 m. These values are exact.

How do I convert miles to feet?

Multiply by 5,280: 1 mi × 5,280 ≈ 5,280 ft. To convert back, divide by the same factor. The factor shown may be rounded.

How can I estimate miles in feet without a calculator?

Multiply by 5300. This is 0.4% above the exact factor (about 5,280), so 1 mi comes out as 5,300 ft instead of 5,280 ft.
