# km to Feet Converter URL: https://speedycalculator.com/calculators/conversion/km-to-feet/ Last updated: 2026-10-25 > Convert kilometres (km) to feet (ft): 1 kilometre = 3,280.8399 ft, so multiply by 3,280.8399 or divide by 0.0003048. Both fields are editable, so you can also type in feet and get kilometres back. ## Inputs - Kilometres (km) ## Results - Feet ## Formula ``` 1 km = 3,280.8399 ft 1 ft = 0.0003048 km ft = km × 3,280.8399 ``` ## Explanation One kilometre is about 3,280.84 feet. Aviation and mountaineering often mix the two: cruising altitude of 11 km is about 36,000 ft. ### How to use the km to Feet Converter - Type the number of kilometres into the **Kilometres** field. Decimals such as 0.5 are fine. - Read the answer in **Feet** – it updates as you type, with no button to press. - To convert the other way, type into **Feet** and the kilometres are recalculated. - Press **Copy results** to copy both values with the page title, or **Copy link** to share this exact conversion. This page converts only km ⇄ ft. Need a different unit? Use the general length converter, where you can choose any “from” and “to” unit. ### How it works Both units measure length, so they are always in the same ratio: one kilometre equals 3,280.8399 feet. The calculator multiplies the number of kilometres you type by 3,280.8399 to give feet, and when you type into the feet field it divides by the same factor to give kilometres. Because the ratio never changes, doubling the kilometres always doubles the feet. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation). ### How to convert kilometres to feet - Write down the value in kilometres, for example **1 km**. - Multiply by the conversion factor 3,280.8399 (because 1 kilometre = 3,280.8399 ft). - 1 × 3,280.8399 = **3,280.8399 ft**. - To go back from feet to kilometres, divide by 3,280.8399 – or multiply by 0.0003048. ### km to ft conversion table KilometresFeetFeetKilometres0.1 km328.08399 ft1 ft0.0003048 km0.5 km1,640.4199 ft2 ft0.0006096 km1 km3,280.8399 ft5 ft0.001524 km2 km6,561.6798 ft10 ft0.003048 km3 km9,842.5197 ft20 ft0.006096 km5 km16,404.199 ft50 ft0.01524 km8.849 km29,032.152 ft100 ft0.03048 km10 km32,808.399 ft1,000 ft0.3048 km11 km36,089.239 ft12 km39,370.079 ft ### What is a kilometre? A kilometre is 1,000 metres. It is the standard unit for road distances, maps, running races and travel in almost every country except the U.S. and UK, where miles are still used on road signs. ### What is a foot? The international foot is exactly 0.3048 m and contains 12 inches. It remains the everyday unit for height, room dimensions and altitude in the U.S., and for aviation altitude worldwide. ### Quick mental conversion For a fast estimate, multiply kilometres by about **3,300** to get feet; the error is about 0.6%. Use the calculator above when you need the exact figure. ### Common mistakes to avoid Mixing the international foot (0.3048 m) with the old u.s. survey foot, confusing nautical and statute miles, and writing decimal feet such as 5.5 ft as “5 ft 5 in” (it is 5 ft 6 in). ## Worked example Inputs — Kilometres: 1 km. Results — **Feet = 3,280.83989501 ft**. ## FAQ **How many feet in a kilometre?** About 3,280.84 ft. **How many feet is 8.849 km (Everest)?** About 29,032 ft. **How do I convert kilometres to feet?** Multiply the number of kilometres by 3,280.8399. For example, 1 km × 3,280.8399 = 3,280.8399 ft. **How do I convert feet back to kilometres?** Divide by 3,280.8399 (or multiply by 0.0003048), or simply type the value into the feet field above. **What is 10 km in feet?** 10 km = 32,808.399 ft. **What is 5 km in feet?** 5 km = 16,404.199 ft. **Is this conversion exact?** Yes. The factor comes from the official definitions of both units (NIST and the SI), so the only difference you may see is rounding in the last displayed digit. **Can I convert to other units on this page?** This page converts only between kilometres and feet.
