Kilometers to Feet (km to ft)

How to convert kilometers to feet

Multiply the kilometers by 3,280.84:

ft = km × 3,280.84

5 km × 3,280.84 = 16,404.2 ft. The factor follows from the exact foot: a foot is 0.3048 m, so a kilometer is 1,000 ÷ 0.3048 = 3,280.839895 feet. The result also shows miles and yards. Because a foot is defined in meters, the answer is exact to as many digits as you need; the only rounding is in the display. To go the other way, divide feet by 3,280.84 — or multiply by 0.0003048.

Races and trails

Trail maps and race courses in the U.S. often give length in miles and elevation in feet, while international ones use kilometers and meters. Converting the course to feet makes it comparable with the climb: a 10K with 1,000 feet of gain rises about 3 feet for every 100 feet of trail, a 3% average grade.

Elevations and flight levels

Altitude in aviation is given in feet worldwide, and mountain heights in feet in the U.S.: an airliner at 10.7 km is at 35,000 feet, and Mont Blanc’s summit, about 4.8 km up, is roughly 15,750 feet. For miles as the answer, see km to miles; for meters, meters to feet; for feet back to miles, feet to miles.

Survey and property distances

Property and survey records in the U.S. are in feet, while maps and GPS apps show kilometers or meters. A parcel 0.4 km deep is 1,312 feet; a road frontage of 0.25 km is 820 feet. For areas, convert both sides to feet and multiply, or use the square footage calculator, which also gives acres for larger lots.

A quick estimate

A kilometer is about 3,300 feet, so multiply by 3,300 for a fast estimate that is 0.6% high: 5 km is about 16,500 feet (16,404). For a mile, a kilometer is just over 0.6 of one. To convert many distances at once — the legs of a route — paste them into Convert a list of values.
