What Is Feet TO Millimeters?
One foot equals exactly 304.8 millimeters. This conversion bridges the gap between imperial construction measurements and metric precision specifications. When American contractors work with imported European hardware, they need to know that a standard 2x4 stud (which is actually 1.5 inches by 3.5 inches, or 38.1 mm by 88.9 mm) fits into structures measured in feet. Aerospace companies designing aircraft in imperial feet must specify fastener holes in millimeters for international suppliers. A standard doorway at 6 feet 8 inches tall is 2032 mm, information needed for ordering metric-sized doors. The exactness of 304.8 mm per foot comes directly from the defined relationship: 12 inches x 25.4 mm = 304.8 mm, making the conversion clean and unambiguous.
Formula
Multiply the foot value by 304.8 to get millimeters. This is exact: 1 foot = 12 inches, and 1 inch = 25.4 mm, so 12 x 25.4 = 304.8 mm.
Best For:
