Picogram

What is a picogram?

A picogram (pg) equals 10^-15 kilogram.

Origin of the picogram

From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).

Where it is used

Single-cell biology and ultratrace chemical analysis.

When and where it was developed

The pico- prefix entered the SI in 1960.
