How this calculator works
The international foot is exactly 0.3048 m and the statute mile is exactly 5,280 of those feet, which makes a mile exactly 1,609.344 m. Feet to miles is therefore a division by 5,280 and miles to feet a multiplication by the same number, with no rounding inside the calculation. The readout is rounded to six significant digits only for display, so a small distance in miles shows as a decimal fraction. The nautical mile is a different unit of exactly 1,852 m and is not used here.
Formula
miles = feet / 5,280. feet = miles x 5,280. 1 mile = 5,280 ft = 1,760 yd = 63,360 in = 1,609.344 m exactly.
Worked example
2,640 ft is 2,640 / 5,280 = 0.5 mi. A 5-mile run is 5 x 5,280 = 26,400 ft. 1,000 ft is 0.189394 mi, and 12 mi is 63,360 ft. To read a mixed answer, divide into whole miles and leftover feet: 12,000 ft is 2 mi plus 1,440 ft.

Frequently asked questions
Is a mile exactly 5,280 feet?
Yes. The statute mile has been defined as 5,280 feet since the international yard and pound agreement of 1959, and the foot is exactly 0.3048 m, so no approximation is involved.
How do I convert feet to miles with a remainder?
Divide by 5,280 and keep the whole part as miles, then multiply the fractional part by 5,280 to get the leftover feet. For 12,000 ft, 12,000 / 5,280 = 2.272727, so the answer is 2 mi and 0.272727 x 5,280 = 1,440 ft.
Is a nautical mile the same as a statute mile?
No. A nautical mile is exactly 1,852 m, or about 6,076.12 ft and 1.15078 statute miles. Aviation and marine work uses the nautical mile, while road distances use the statute mile.
Why does a short distance in miles look so small?
A mile is a long unit, so most everyday distances in feet become fractions of a mile. The page shows six significant digits, so 100 ft reads as 0.0189394 mi rather than being rounded to zero.
