Conversions from a multiple
or submultiple to the basic units of meters, liters, or grams can be done using
the table. For example, to convert from kilometers to meters, multiply by 1,000
(9.26 kilometers equals 9,260 meters) or to convert from meters to kilometers,
multiply by 0.001 (9,260 meters equals 9.26 kilometers).
