Which prefix represents 10^3?

Explanation:
Think of metric prefixes as a way to scale a unit by powers of ten. 10^3 means a thousand, and that is conveyed by the prefix kilo. So a kilometer is 1000 meters, and a kilogram is 1000 grams. Other options point to different scales: mega is 10^6 (a million), milli is 10^-3 (one thousandth), and nano is 10^-9 (one billionth). Thus the prefix for 10^3 is kilo.
