Mile
A mile (mi) is a well-known unit of length in the imperial system, equal to 5,280 feet or about 1.609 kilometers. It is commonly used in the United States and the United Kingdom to measure travel distances, road signs, running events, and property boundaries. The mile provides a practical scale for everyday movement and transportation.
Because much of the world uses kilometers, conversions between miles and metric units are frequently needed. A unit converter helps ensure quick and accurate results—whether planning a road trip or checking your workout distance.
Decimeter
A decimeter (dm) is a metric unit of length equal to one-tenth of a meter. It sits between centimeters and meters in size, making it helpful for measurements that are too large for centimeters but too small for full meters. Although not as commonly used in day-to-day tasks, the decimeter is important in education, engineering, and scientific contexts.
Because it is part of the metric system, converting decimeters into other units is simple—for example, 1 decimeter = 10 centimeters and 0.1 meters. A unit converter can help you switch quickly between measurements when precision is important.
