Whether you're looking at trail distances, altitude readings, or comparing metric and imperial distances, this calculator converts kilometers to feet using the precise factor of 3280.84 feet per kilometer.

How It Works

The calculator multiplies your kilometer value by 3,280.84, derived from the exact definition: 1 foot = 0.3048 meters exactly, so 1 meter = 3.28084 feet, and 1 kilometer = 1,000 meters, giving 1 km = 3,280.84 feet. Unlike within-metric conversions, this is not a round number because the foot is an independently defined imperial unit. Common uses include converting trail distances for US audiences, aviation contexts where altitude is reported in feet while horizontal distances may be in kilometers on aeronautical charts, and comparing foreign property or land areas. Key reference conversions: 1 km = 3,281 ft, 5 km = 16,404 ft, 10 km = 32,808 ft, 42.195 km (full marathon) = 138,435 ft.

Frequently Asked Questions

How many feet are in a kilometer?
There are 3280.84 feet in one kilometer.
Why is this conversion not a round number?
The foot is an imperial unit not derived from the metric system, so the conversion factor is not a whole number.
Can I use this for altitude conversions?
Yes. Altitude is commonly expressed in feet in aviation and in meters or kilometers in science.
How many feet in a kilometer?
