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 Kilometers (1 ft = 0.0003048 km). Foot is used in US construction and real estate floor plans and in aviation altitude worldwide. Kilometer is used in 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).
