The SI unit of length is the meter (symbol: m). It is the fundamental unit of length in the International System of Units (SI), commonly used worldwide. Derived units based on the meter include the kilometer (1,000 meters), centimeter (one-hundredth of a meter), and millimeter (one-thousandth of a meter). These units measure everything from microscopic distances to geographic spans across the globe.
1 kilometer (km) = 1,000 meters (m)
1 meter (m) = 1 meter
1 decimeter (dm) = 0.1 meters (10 decimeters = 1 meter)
1 centimeter (cm) = 0.01 meters (100 centimeters = 1 meter)
1 millimeter (mm) = 0.001 meters (1,000 millimeters = 1 meter)
The primary unit of length in the Centimeter-Gram-Second (CGS) system is the centimeter (cm). The CGS system is a variant of the metric system that is less commonly used today but is still relevant in some scientific contexts, particularly in physics.
1 centimeter (cm) = 1 centimeter
1 millimeter (mm) = 0.1 centimeters (10 millimeters = 1 centimeter)
1 decimeter (dm) = 10 centimeters (1 decimeter = 10 centimeters)
The MKS (Meter-Kilogram-Second) system is a scientific system of measurement that uses the meter as the base unit of length. This system forms the foundation of the International System of Units (SI), which is globally accepted for scientific and commercial use.
