Common length conversions for travel, sports, and everyday use
| Kilometers (km) | = | Feet (ft) | Practical Context |
|---|---|---|---|
| 0.1 km | = | 328.08 ft | Short city block |
| 0.5 km | = | 1,640.42 ft | 5-minute walk |
| 1.0 km | = | 3,280.84 ft | 10-minute walk |
| 1.609 km | = | 5,280 ft | 1 mile |
| 5.0 km | = | 16,404.20 ft | 5K race distance |
| 10.0 km | = | 32,808.40 ft | 10K race distance |
| 42.195 km | = | 138,435 ft | Marathon distance |
| 100 km | = | 328,084 ft | Ultra marathon distance |
All conversions use the factor: 1 km = 3,280.84 ft
Common questions about kilometers and feet
There are approximately 3,280.84 feet in a kilometer. This conversion is based on the fact that one kilometer equals 1,000 meters, and one meter is approximately 3.28084 feet. The exact value is derived from the international definition of a foot as 0.3048 meters, so:
1 kilometer = 1,000 meters
1 meter = 1 / 0.3048 feet ≈ 3.28084 feet
Thus, 1 kilometer = 1,000 × 3.28084 ≈ 3,280.84 feet.
For practical purposes, this is often rounded to 3,281 feet.
The conversion factor comes from the definition of the meter in terms of imperial units:
1 meter = 3.28084 feet
1 kilometer = 1,000 meters = 1,000 × 3.28084 feet = 3,280.84 feet
This precise conversion factor was established when international standards for units were formalized.
Use kilometers (km) for:
Use feet (ft) for:
Since 1 mile = 5,280 feet, and 1 kilometer = 3,280.84 feet, you can use this conversion:
1 mile = 1.60934 kilometers
kilometers = miles × 1.60934
miles = kilometers ÷ 1.60934
For a quick estimate, multiply miles by 1.6 or divide kilometers by 1.6 to get a close approximation.
Kilometers are used in nearly all countries as part of the metric system. The primary exceptions are:
Even in countries using primarily metric units, feet are still used in some specialized contexts like aviation.
The precise conversion factor is 1 kilometer = 3280.8398950131 feet. For most practical purposes:
This converter uses the precise 3,280.84 factor for accurate results in all applications.
