What power of 10 is associated with the prefix "nano"?

The prefix "nano" is associated with the power of 10 to the negative ninth, or 10^−9. This prefix is commonly used in various scientific and engineering contexts to denote quantities that are very small. For example, one nanometer is one billionth of a meter, and this microscopic scale is relevant in fields like electronics and materials science.

The other options represent different prefixes: "micro" corresponds to 10^−6, "pico" to 10^−12, and "femto" to 10^−15. Understanding these prefixes is vital for interpreting and expressing measurements accurately in technical disciplines, making the knowledge of such conversions crucial for engineers and scientists alike.
