Non-SI metric units refer to metric units of measurement that are not part of the International System of Units (SI), which is the standardized system of measurement adopted worldwide. While the SI system is based on a set of base units (like meters for length, kilograms for mass, seconds for time, etc.), non-SI metric units include other units that may still be expressed in multiples and fractions of the base ten system but do not have official status within the SI framework.

One centimeter is equal to one hundredth of a meter (1 cm = 0.01 m).
The Metre–tonne–second system of units (MTS) is a coherent system of units for physical quantities that serves as an alternative to the more widely known SI (International System of Units).
