Convert Feet to Kilometers
1 foot is 0.0003048 km. One foot is exactly 0.0003048 kilometers.
One foot is 3.0480 × 10^-4 kilometers. To convert feet to kilometers, multiply by 3.0480 × 10^-4; to go the other way, divide by 3.0480 × 10^-4 or multiply by 3280.8399. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. Twelve inches, or exactly 0.3048 meters.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: feet to kilometres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert feet to kilometers? The converter and the working
- 1.Take the measurement in feet.
- 2.Multiply by 3.0480 × 10^-4 — that is how many kilometers fit in one foot.
- 3.To go back the other way, divide by 3.0480 × 10^-4, or multiply by 3280.8399.
Worked example: 25 feet to kilometers
- Formula
- ft × 3.0480 × 10^-4 = km
- Arithmetic
- 25 × 3.0480 × 10^-4 = 0.01 km
- Answer
- 25 ft = 0.01 km
The factor is rounded for display; the figure above is computed from the full value.

What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
What is a kilometer?
One thousand meters, and about 0.621 miles.
How many kilometers are in a foot?
One foot is 3.0480 × 10^-4 kilometers. Going the other way, one kilometer is 3280.8399 feet. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
