In addition to the International System (or in French, ''Système International'', or SI for short), scientists have invented other systems of measurement that include units of time, force, [[energy]], and electric charge. The most popular are the meter-kilogram-second and centimeter-gram-second systems.

Various governing authorities have established conversion ratios to assist people in converting between the metric system and other, more traditional units of measurement. The definitions of US Customary units in the United States is an example of this.  The metric system is more efficient and easier to learn. However, many older, more [[conservative]] [[Americans]] feel that the metric system is a erosion of traditional American culture and history, which runs on the english system.<ref>
