The fundamental units of the meter and kilogram are not the familiar units of feet or pounds that are typically used in the United States. It is defined by taking the fixed value of the speed of light in vacuum and is expressed as m. Some derived units are relatively complex when expressed in terms of the basic units, and are therefore given specific names for convenience e e. Table 1. For each non-SI unit, it gives the name, symbol, and factor to convert to the corresponding SI unit. The use of „g‟ is not required. m s-1 is a derived unit, whereas m and s are fundamental (base) units. SI is built upon 7 base quantities and their associated units see Table I. Newell . The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent: SI base units. Electrical current is the Table A1-4.
