The basic unit of length (on a ruler) is the meter, symbol m.
Two smaller units (decimal fractions of the meter are:
centimeter cm (0.01 of the meter)
millimeter mm (0.001 of the meter)
The meter is slightly larger than a yard. Approximately 39.37 inches.
Conversely one inch is 2.54 centimeters exactly.
There are several other prefixes the multiply or divide SI units in powers of 10.

In most of the world, everything that is measured, is measured in SI units. Time, distance, mass, weight, area, volume and so on.
International System of Units (SI)

My common 30m builders steel tape is graduated in cm and m.
Scientists agreed to use the SI units worldwide because they provide a standardized system of measurement that is based on fundamental physical constants, making it more accurate and consistent. This allows for international collaboration in research and ensures that measurements are easily understood and reproducible across different scientific disciplines.
Kilogram, second, meter, meters cubed, and kelvin.
volts, amperes, ohms, hertz, watts
most of the world does SI so more people can understand with it in SI units

CGS is NOT common nowadays. MKS is common because the SI, the international system of units, is based on it.
There are several, collectively known as the SI units.
The SI system of units is the international system of measurements. It is also known as the "metric system", although technically there are different (but similar) metric systems. The SI system is used in most countries in the world; both scientists and common people generally use SI units such as meter, kilogram, second, square meter, etc.; some common exceptions to this are units of time (the official unit is the second, but other units are used as well), speed (the official unit is meters/second, but kilometers/hour are quite common), and temperature (the official unit is the Kelvin, but the degree Celsius is more common in a non-scientific context).
