Kilometres to Feet Conversion Calculator
Instantly convert kilometres to feet, with feet-and-inches, yards and miles shown alongside. The international foot is defined as exactly 0.3048 metres, so no measurement error enters the conversion.

Metres in one kilometre
1 km = 1,000 m = 1,000Exact SI definition. - 2
Metres per foot
1 ft = 0.3048 m = 0.3048Exact international foot since 1959. - 3
Feet per kilometre
1,000 ÷ 0.3048 = 3,280.8399 - 4
Convert to feet
1 × 3,280.8399 = 3,280.840
How does this calculator work?
Multiply kilometres by 3280.8399 to get international feet (based on 1 ft = 0.3048 m exactly). Example: 1 km = 3280.84 ft, 5 km = 16,404.2 ft. The calculator also shows feet-and-inches, yards and miles in one step.
Formula
How this is calculated
The international foot has been defined as exactly 0.3048 metres since 1959, and one kilometre is exactly 1000 metres. Combining these exact definitions gives 1 km = 1000 ÷ 0.3048 = 3280.839895... feet — a repeating decimal that cannot be rounded without introducing some small error, so this calculator displays as many decimal places as needed.
From feet, other imperial units follow directly: one yard is three feet, one mile is 5280 feet (equivalently 1.609344 km exactly). Inches are the decimal fraction of feet multiplied by 12. All conversions here use the international (not US survey) definitions and are purely arithmetic — no constants that could drift or expire.
Common reference: 1 km ≈ 3281 ft, 3 km ≈ 9843 ft, 5 km ≈ 16404 ft (a 5K race), 42.195 km ≈ 138,435 ft (a marathon).
Frequently asked questions
1 kilometre = 3280.8399 feet (exactly 1000 ÷ 0.3048). For a quick rough estimate, multiply km by 3280 or by 3281.
Multiply kilometres by 3280 for a close estimate, or by 3000 for a fast rough check. For example, 2 km ≈ 6560 ft. The exact factor is 3280.84.
Almost, but not exactly. The international foot = 0.3048 m exactly; the US survey foot = 1200/3937 m ≈ 0.30480061 m — about 2 mm per km difference. This calculator uses the international foot, which is standard worldwide.
