In short
How many feet are in a mile?
Exactly 5,280 feet. Divide feet by 5,280 to get miles, so 2,640 ft is half a mile. The odd number comes from the furlong: a mile is 8 furlongs, a furlong is 40 rods, and a rod is 16.5 feet — and 8 times 40 times 16.5 is 5,280.
This is the statute mile. A nautical mile is a different unit entirely, at exactly 1,852 metres or about 6,076 feet.

The formula, worked line by line
One division by an exact integer, and the integer is the whole story. A mile is 5,280 feet because it was fitted to a furlong that already existed, not because anyone chose the number for its own sake.
“Eight furlongs of forty rods, each rod sixteen and a half feet — 5,280.”
Since 1959 the foot has been defined as exactly 0.3048 metres, which makes the mile exactly 1,609.344 metres. So the statute mile is now an exact metric quantity, defined through a system it predates by centuries.
miles = feet / 5,280
1 rod = 16.5 ft, 1 chain = 66 ft, 1 furlong = 660 ft
8 x 660 = 5,280 ft = 1 mile
1 mile = 1,609.344 m exactly
1 nautical mile = 1,852 m = about 6,076.12 ft- Feet

Under a fifth of a mile. Rounded to two decimals that becomes 0.19, which is fine for a walk and loses about 30 feet — worth keeping four places if the figure is going into anything measured.
Why 1.6 km is not a mile
The mile is 1.609344 kilometres. The shorthand 1.6 is 0.58 percent short, which is about 9 metres per mile — invisible on a car journey and material over a marathon, where it accumulates to roughly 250 metres.
Where the old units survive
- Furlong
- horse racing distances
- Chain
- a cricket pitch is 22 yards, one chain
- Rod
- older land descriptions and deeds
- Acre
- one chain by one furlong
None of these is obsolete in the sense of being unusable. They are alive in the specific places where re-measuring everything would have cost more than keeping the unit.
How to use the feet to miles converter
Divide by 5,280. The factor is exact — a mile has been exactly 5,280 feet for centuries, and since 1959 the foot itself has been exactly 0.3048 metres, which makes the mile exactly 1,609.344 metres with nothing left to measure.
The number looks arbitrary and is not. It comes from a chain of older units that were themselves round: eight furlongs to the mile, forty rods to the furlong, sixteen and a half feet to the rod. Multiply those together and 5,280 falls out. Each link is tidy; only the product looks strange.

a different unit entirely
The rod at 16.5 feet is the odd link, and it is the one that explains the whole imperial land system. Four rods make a chain of 66 feet; forty make a furlong of 660. An acre is one chain by one furlong, which is 43,560 square feet. Every awkward figure in the system traces back to that single length.
Which is a useful thing to know about units generally: when two systems collide, the one tied to land tends to win, because changing it would have meant re-surveying every field. The mile was abstract enough to move and the furlong was not.
- 1/8 mile, one furlong
- 660 ft
- 1/4 mile
- 1,320 ft
- 1/2 mile
- 2,640 ft
- 3/4 mile
- 3,960 ft
- 1 mile
- 5,280 ft
- 5 miles
- 26,400 ft
The eighths all come out whole, which is the practical benefit of a mile built from eight furlongs rather than from a round number of feet.
Convert miles into kilometers instead
For the metric distance, that page uses the exact 1.609344 factor and shows why 1.6 is a shortcut rather than the number.

The chain of units behind 5,280
Read from the bottom up, the imperial land system is a stack of small whole-number ratios. It only looks irrational when you compare the two ends and skip everything between them, which is exactly what a conversion factor does.
- 1 rod
- 16.5 feet
- 4 rods
- 1 chain = 66 feet
- 10 chains
- 1 furlong = 660 feet
- 8 furlongs
- 1 mile = 5,280 feet
- The mile
- 5,280 feet exactly
Four steps, every one of them a small whole number. The furlong survives today mainly in horse racing, and the chain in the dimensions of a cricket pitch, which is 22 yards — exactly one chain.
The same chain produces the acre, which is why land and distance in the imperial system share their awkwardness. One chain by one furlong is 66 by 660 feet, or 43,560 square feet, and a square mile is 640 of those acres. None of it is arbitrary; all of it is inherited.
Three different miles, and only one of them is this one
The word covers more than one unit, and they are far enough apart to matter. The statute mile of 5,280 feet is the one used on land in the United States and the United Kingdom. The nautical mile is exactly 1,852 metres, about 6,076 feet — roughly fifteen percent longer — and is used at sea and in the air.
- Statute mile
- 5,280 ft = 1,609.344 m exactly
- Nautical mile
- 1,852 m exactly = about 6,076.12 ft
- The difference
- the nautical mile is about 15 percent longer
- A knot
- one nautical mile per hour
The nautical mile was defined to approximate one minute of latitude, which is why it is a navigation unit rather than a land one. It is now fixed at exactly 1,852 metres by international agreement.
There was also a US survey mile, based on the slightly longer survey foot and about 3.2 millimetres longer per mile. It was deprecated along with the survey foot at the end of 2022, so for any new measurement there is one statute mile and the distinction is a legacy-data concern.
