Background
The two major systems of measurement are
the Metric System and the English System. The Metric System is the most
common system of measurement and is a tenbased system, meaning that each
subsequent measurement unit is a multiple of ten from the fundamental unit.
The English System of measurement is the common system for the United States and
has no common number base such as the Metric System. Many of the English
units today are defined in terms of the Metric System due to its accuracy and
widespread use.
