About Foot and Kilometer
The foot is defined as exactly 0.3048 meters (12 inches) under the 1959 international yard and pound agreement. US construction, real estate, and aviation altitude all run on feet. The kilometer is 1,000 meters, the standard unit for road distances, maps, and geography in most of the world. Road signs, running races, and vehicle odometers outside the US and UK all use it. One Foot equals 0.0003048 Kilometer (1 ft = 0.0003048 km). Foot to Kilometer conversion comes up most often in US construction and real estate floor plans and in aviation altitude worldwide, typically when figures need restating for road distances and signage outside the US.
Precision and Rounding: Length factors between metric and imperial units are exact by definition (1 ft = 0.3048 m since 1959), so any rounding error comes from display precision, not the factor. Two or three decimal places suit carpentry and DIY work; machining and surveying often require four or more.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
