This converter turns feet into kilometers instantly, using the exact factor 1 foot = 0.0003048 kilometers. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
Twelve inches, or exactly 0.3048 metres — still standard for human height and aviation altitude in the US. One thousand metres — the standard road-distance unit almost everywhere outside the US and UK.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
feet- The amount you are converting, measured in feet
0.0003048- The exact number of kilometers in one foot
kilometers- The converted result
How it works, step by step
- Enter the number of feet you want to convert.

- The result is displayed in kilometers, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 feet
Multiply 5 by 0.0003048. That gives 0.001524 kilometers. A quick sanity check: one foot is smaller than one kilometer, so the number should get smaller — and it does.
Converting 72 feet
72 × 0.0003048 = 0.021946 kilometers. Working backwards, 0.021946 ÷ 0.0003048 returns 72 feet, which confirms the factor is applied the right way round.
