Metric Interrelationships

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)
