Which prefix equals 10^-3?

Explanation:
SI prefixes stand for powers of ten, letting us describe fractions or multiples of a base unit. A value of 10^-3 means one thousandth of a unit. The prefix for one thousandth is milli, so 1 milli = 0.001 of the base unit. That’s why millimeters (0.001 meters) or milliliters (0.001 liters) use this prefix. The other prefixes map to different powers of ten: micro is 10^-6 (one millionth), centi is 10^-2 (one hundredth), and mega is 10^6 (one million). Therefore, 10^-3 corresponds to milli.
