Table A-1 a-Cont.
Prefixes The following prefixes, in combination with the basic unit names, provide the multiples and
submultiples in the International System. For example, the unit name "meter," with the prefix "kilo" added, produces "kilometer," meaning "1000 meters."

In using conversion factors, it is possible to perform division as well as the multiplication process shown here. Division may be particularly advantageous where more than the significant figures published here are required. Division may be performed in lieu of multiplication by using the reciprocal of any indicated multiplier as divisor. For example, to convert from centimeters to inches by division, refer to the table headed "To convert from inches" and use the factor listed at "centimeters" (2.54) as divisor.
