Picometre
From Wikipedia, the free encyclopedia
A picometre (American spelling: picometer, symbol pm) is a unit of length in the metric system, equal to one millionth-millionth of a metre, which is the current SI base unit of length. It can be written in scientific notations as 1×10−12 m (engineering notation) or 1 E-12 m (exponential notation) — both meaning 1 m / 1,000,000,000,000.
femtometre <<< picometre <<< nanometre <<< micrometre <<< millimetre < centimetre < decimetre < metre < decametre < hectometre < kilometre
It equals a millionth of a micrometre (formerly called a micron), and was formerly called micromicron or bicron.
It equals a hundredth of an Ångström, an internationally recognized non-SI unit of length.
