What does the prefix kilo- signify?

Explanation:
Kilo- means thousand. In the metric system, prefixes scale a unit by powers of ten, and kilo- specifically multiplies by 10^3. So a kilometer is 1000 meters, and a kilogram is 1000 grams. The idea is that kilo- sits at 1000, not at a million, hundred, or ten—the prefixes for those scales are mega- (10^6), hecto- or centi- (for 100 or 1/100), and deca- (10) respectively. If you had 3 kilometers, that would be 3000 meters.
