Conversion Unit Definitions
What is a Millimeter?
The millimeter is a unit of length in the metric system. It is defined as one-thousandth of a meter or 0.001 meters. The millimeter is primarily used to measure very small distances or dimensions.
What is a Kilometer?
A kilometer is a unit of length in the metric system, derived from the meter. It is defined as 1,000 meters or approximately 0.621 miles. The kilometer is commonly used to measure longer distances, such as the length of roads, distances between cities, or geographical features.

What Length Units Are Supported?
| Name | Symbol | Description |
|---|---|---|
| inch | '' | The inch (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. It is equal to 1/36 yard or 1/12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb. |
| centimeter | cm | The centimeter is a unit of length in the metric system, which is widely used around the world. It is defined as one-hundredth of a meter or 0.01 meters. The centimeter is primarily used to measure small distances, lengths, and dimensions. |
| millimeter | mm | The millimeter is a unit of length in the metric system. It is defined as one-thousandth of a meter or 0.001 meters. The millimeter is primarily used to measure very small distances or dimensions. |
| foot | ft | The foot (pl. feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet. |
| yard | yd | The yard is a unit of length primarily used in the United States and a few other countries, particularly those with historical ties to the British Empire. It is defined as 3 feet or 36 inches. The yard is commonly used to measure longer distances or dimensions, especially in everyday contexts like construction, landscaping, and sports. |
| meter | m | The meter is a unit of length in the metric system, which is the most widely used system of measurement around the world. It is defined as the distance traveled by light in a vacuum during a specific time interval. The meter is the fundamental unit of length in the International System of Units (SI). |
| kilometer | km | A kilometer is a unit of length in the metric system, derived from the meter. It is defined as 1,000 meters or approximately 0.621 miles. The kilometer is commonly used to measure longer distances, such as the length of roads, distances between cities, or geographical features. |
| mile | mi | The mile is a unit of length primarily used in the United States and a few other countries that have historical ties to the British Empire. It is defined as 5,280 feet or approximately 1.609 kilometers. The mile is commonly used to measure longer distances, especially in transportation, sports, and everyday contexts in countries that have not fully adopted the metric system. |
