picometer
Atom-scale length unit
A picometer is one trillionth of a meter—a unit so small it measures distances between atoms.
Written as 10⁻¹² meters, it's useful in chemistry and physics for describing atomic radii and bond lengths: The carbon-carbon bond in diamond is about 154 picometers.
Also spelled picometre.
