How Many? A Dictionary of Units of Measurement Â© Russ  Rowlett and the University of North Carolina at Chapel  HillTable of  ContentsAbout the DictionaryUsing the DictionaryCGS and MKS Units The result was two clusterings of metric units in science and engineering. One cluster, based on the centimeter, the gram, and the second, is called the CGS system. The other, based on the meter, kilogram, and second, is called the MKS system. When we say, for example, that the dyne is the CGS unit of force, this determines its definition: it is the force which accelerates a mass of one gram at the rate of one centimeter per second per second.
