Which prefix corresponds to one thousandth of a unit?

Explanation:
Prefixes in the metric system indicate powers of ten. One thousandth corresponds to 10^-3, which is represented by milli. So a millimeter is 0.001 meters, for example. Nano is 10^-9 (one-billionth), micro is 10^-6 (one-millionth), and mega is 10^6 (one million times larger). This is why milli is the correct prefix for one thousandth of a unit.
