metric unit for length
mm, cm, m, km
The standard unit of length in the metric system is the meter. Other units of length and their equivalents in meters are as follows:
1 millimeter = 0.001 meter
1 centimeter = 0.01 meter
1 decimeter = 0.1 meter
1 kilometer = 1000 meters
The metric unit for length is the meter (m). The meter is the base unit of length in the International System of Units (SI).
To convert between different metric units of length, you can use the following prefixes:
- Kilometer (km): One kilometer is equal to 1,000 meters.
- Centimeter (cm): One centimeter is equal to 0.01 meters.
- Millimeter (mm): One millimeter is equal to 0.001 meters.
To convert between these units, you can use multiplication or division by the appropriate conversion factor. For example, to convert 5 kilometers to meters, you would multiply 5 by 1,000 to get 5,000 meters. Similarly, to convert 200 millimeters to meters, you would divide 200 by 1,000 to get 0.2 meters.
It's important to note that the metric system is a decimal-based system, which makes conversions between different metric units relatively straightforward.
