About Millimeter and Foot

The millimeter is one thousandth of a meter. Engineering and manufacturing drawings in metric countries are dimensioned almost exclusively in millimeters to avoid decimal points. 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. One Millimeter equals 0.003280839895 Feet (1 mm = 0.003280839895 ft). Millimeter is used in engineering and CAD drawings and in manufacturing tolerances. Foot is used in US construction and real estate floor plans.

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).
