A picogram (pg) is a unit of mass in the metric system, equal to one trillionth of a gram, or 10^-12 grams. It is often used in scientific contexts to measure extremely small quantities, such as in biochemistry or pharmacology. To put it in perspective, a picogram is to a gram what a grain of salt is to a typical adult's body weight.
"Pica" is a prefix, not a base unit, so there isn't a conversion factor available for this. What kind of "expert" is this? (Pica is a type size. Pico is a prefix. You must have been educated in a government school.)
