One millimetre equals 0.00328084 feet, or equivalently 1 foot = 304.8 mm. To convert mm to feet, divide by 304.8. For feet-and-inches, first divide by 25.4 to get total inches, then separate: whole inches / 12 = feet, remainder = inches. Example: 1500 mm ÷ 25.4 = 59.055 in = 4 ft 11.06 in. Millimetres are used in precision measurement; feet are used in US construction and architecture.
Converting between mm and feet is common when working with European metric drawings in US construction settings, or when US equipment specifications are used with metric tools. A standard interior door in the UK is 1981 mm (= 6.5 ft = 6 ft 6 in). A ceiling height of 2438 mm = 8 feet (standard US residential). Metric rulers and imperial tape measures are commonly used side-by-side in mixed-standard workplaces.

Millimeters to Feet for US Construction and Trade
Dividing millimeters by 304.8 converts to feet. Metric-standard component dimensions from international suppliers must be converted to feet and inches for US contractors working with feet-based measuring tools and US code compliance documentation. A metric door frame of 2000 mm height equals approximately 6.562 feet (6′6.74″). Structural steel metric sections (HEA, HEB, IPE profiles) specify depth and width in millimeters; US engineers need feet-and-inches equivalents for code-check software that uses US customary units. Lumber sold in metric markets is sized in millimeters; converting to feet helps US buyers estimate quantities and compare against US nominal lumber sizes. Rebar and reinforcing mesh in metric projects use mm bar diameters and mm spacing; structural drawings for US contractors need these converted to inches and then packaged into feet-based layout dimensions.
