11mm

11 millimeters (11 mm) is a unit of length in the metric system, equal to 0.011 meters. It is also 1.1 centimeters and about 0.433 inches. In micrometers, it is 11,000 μm.

The prefix milli- denotes a thousandth, so 11 mm is 11 thousandths of a meter. This places 11 mm firmly in the range of small, precise measurements often used in engineering, manufacturing, and consumer products.

11 mm is commonly used to express dimensions such as thickness, bore diameters, diameters of small shafts, and other tolerances in parts and assemblies. It also appears in packaging specifications, medical devices, electronics enclosures, and sporting goods where compact, standardized measurements are important. In many regions, millimeter-scale measurements are standard for technical drawings and manufacturing specifications, reflecting the widespread adoption of the SI system.

The millimeter is a base unit in the International System of Units (SI). It is widely used internationally for everyday measurements and technical specifications, particularly outside regions where customary units like inches remain common.
