Question: 1 / 400

What does the prefix x10^-3 represent?

kilo

milli

The prefix x10^-3 represents "milli," which is a standard metric prefix used in the International System of Units (SI). In this context, "milli" signifies a factor of one-thousandth (1/1000) of a unit. Therefore, when a quantity is expressed with the prefix "milli," it means that the value has been divided by 1000. For example, 1 millimeter (mm) is equal to 0.001 meters, and 1 milligram (mg) is equal to 0.001 grams.

In contrast, "kilo" refers to a factor of one thousand (10^3), "mega" signifies one million (10^6), and "giga" represents one billion (10^9). Hence, "kilo," "mega," and "giga" represent much larger quantities than "milli," which fundamentally highlights why the prefix x10^-3 corresponds specifically to "milli." Understanding these metric prefixes is crucial in various scientific and medical contexts, where precise measurements are imperative.
