In CGS system, units are compared to a standardized measure: meter was defined as being one ten-millionth part of a quarter of the earth's circumference and 100 centimeters equals a meter.
The International System of Units, universally abbreviated SI (from the French Le Système International d’Unités), is the modern metric system of measurement. The SI is the dominant measurement system used in science and international commerce. In recognition of this fact, Congress has designated the metric system of measurement as the
