The kilometer
The kilometer (km) equals exactly 1,000 meters. It is the standard unit for road distances in almost every country except the United States and the United Kingdom. A 5K running race is 5 kilometers; a marathon is 42.195 km.

1 km = 3280.84 ft (kilometer → foot)
1 km = 3280.84 ft
1 kilometer equals 3280.84 feet. To convert kilometers to feet, multiply the kilometer value by 3280.84. For quick reference: 1 km = 3280.84 ft, 5 km = 16404.2 ft, 10 km = 32808.4 ft, 100 km = 328084 ft.
Formula
Feet = Kilometers × 3280.84Quick
When to use kilometers → feet
Kilometres to feet divides by 0.0003048 — equivalently, multiplies by 3280.84 (1 km = 1000 ÷ 0.3048 ft). Everest at 8.849 km is about 29 032 ft; a 10 km airliner cruise altitude is 32 808 ft. Aviation is where this conversion lives: flight levels and altitudes are quoted in feet almost worldwide, while terrain and airspace charts in metric countries use kilometres and metres. The factor 3280.84 is itself rounded; for altimetry-grade work convert via the exact 0.3048 and round only the final figure.
Mountaineers logging a route's horizontal distance in kilometres from a GPS track still think in feet when estimating elevation gain, since most Western climbing guidebooks quote vertical relief that way even on metric peaks. A 4 km approach hike sits alongside a guidebook's 3,200 ft elevation gain figure — converting the 4 km to 13,123 ft of horizontal distance lets a climber judge the grade, roughly 24%, before committing to the route. Keep horizontal and vertical figures in the same unit before dividing one by the other for a slope estimate.
