If you see the prefix pico-, what exponent does it represent?

Explanation:
Pico means one trillionth of a unit, which is 10^-12. So quantities with the pico prefix are scaled by 10^-12 (for example, 1 picometer is 1 × 10^-12 meters). This is why the exponent corresponding to pico is -12. The other prefixes shown correspond to different exponents: nano is 10^-9, micro is 10^-6, and kilo is 10^3. Therefore, 10^-12 is the match for pico.
