Before a nanometre, the next smaller unit of measurement is a picometre, which is one trillionth of a metre (10^-12 metres). The metric prefix "pico-" denotes this scale, with one nanometre equaling 1,000 picometres. In terms of scale, a nanometre is often used to measure things at the atomic and molecular level, while picometres are used for even smaller measurements, such as atomic diameters.
