Which prefix represents 10^-6?

Explanation:
Understanding SI prefixes helps you read and compare very small quantities. Each prefix stands for a power of ten, so the one that equals 10^-6 is micro. This means one unit scaled by micro is one millionth of that unit—for example, a micrometer is one millionth of a meter, and a microsecond is one millionth of a second. The other prefixes shown correspond to different scales: nano is 10^-9 (one billionth), pico is 10^-12 (one trillionth), and milli is 10^-3 (one thousandth). So micro is the correct representation for 10^-6.
