This page lists some products that are measured or designed using metric units. For example, automobiles, light trucks, farm and construction equipment, bicycles, and motorcycles fall into this category. (The main products page shows examples of items that are packaged in even metric sizes.)
Some of these products have always been built to metric standards, such as 35 mm film, snow-ski and snowboard lengths. Other products have more recently changed to labeling in metric system units.
