Which prefix corresponds to a factor of one thousand?

Explanation:
In the metric system, prefixes modify a unit by powers of ten. The one that corresponds to a factor of one thousand is kilo-, with the symbol k. It means 1 kilo-unit equals 1,000 of the base units (for example, 1 kilometer = 1,000 meters, 1 kilogram = 1,000 grams). The other prefixes shown represent different powers of ten: mega- is 10^6 (a million), hecto- is 10^2 (a hundred), and deca- is 10^1 (ten). So kilo- is the prefix that denotes thousand.
