Facts about the Millimeter
The millimeter (mm) is one-thousandth of a meter and is commonly used in fields that require precision, such as engineering, machining, and medicine. It is also widely used in tools like rulers, micrometers, and mechanical part specifications. Millimeters are ideal for measuring thickness, gaps, and tolerances.
Facts about the Kilometer
The kilometer (km) is a metric unit of length equal to 1,000 meters. It is most commonly used to measure long distances, especially in transportation and geography. Road signs, GPS systems, and athletic events like marathons often use kilometers. The term comes from the Greek words 'khilioi' (thousand) and 'metron' (measure).
