What does the prefix pico represent?

Explanation:
Pico represents 10^-12, one trillionth of the base unit. In the SI prefix sequence, each step down makes the value smaller, so pico is smaller than nano (10^-9) and even smaller than micro (10^-6). For concrete examples, a picometer is 1e-12 meters and a picosecond is 1e-12 seconds. This tiny scale is why pico corresponds to 10^-12.
