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). ____________________________________________________________________________ Prefix Symbol Length, weight, or capacity Area Volume exa E 10 18 10 36 10 54 peta P 10 15 10 30 10 45 tera T 10 12 10 24 10 36 giga G 10 9 10 18 10 27 mega M 10 6 10 12 10 18 hectokilo hk 10 5 10 10 10 15 myria ma 10 4 10 8 10 12 kilo k 10 3 10 6 10 9 hecto h 10 2 10 4 10 6 basic unit -
