About the Millimeter (mm)
The millimeter (symbol: mm) is a unit of length in the International System of Units (SI). It is defined as one-thousandth of a meter. As a metric unit, it is used worldwide for scientific, engineering, and commercial applications.
The millimeter is the preferred unit of measurement for technical drawings and manufacturing specifications where high precision is required. Because it is part of a decimal system, it is extremely easy to convert to centimeters (10 mm = 1 cm) or meters (1,000 mm = 1 m). For visualization, a standard credit card is approximately 0.76 mm thick, and a small paperclip is about 1 mm wide.
