What is the metric prefix for 10^-12?

Explanation:
Understanding how metric prefixes relate to powers of ten helps you quickly read and compare sizes. Pico- corresponds to 10^-12, which means one trillionth of a unit. That makes 1 picometer or 1 picogram extremely small, well below the scales of the nano- (10^-9), micro- (10^-6), and milli- (10^-3) prefixes, since 10^-12 is smaller than all of those by factors of 1000, 1000, and 1,000,000, respectively. So the prefix for 10^-12 is pico- (p).
