About These Units

About Bohr

The Bohr is a unit of distance commonly used in particle physics. It was named after the Danish physicist Niels Bohr (1885-1962), who explained the structure of atoms in a famous paper in 1913. The Bohr radius represents the mean distance between the proton and the electron in an unexcited hydrogen atom. It equals about 52.918 picometers (pm), or 52.918 x 10e-12 meter.

About Millimicron

A unit of metric measurement 1000 millimeters equal one meter, 10 millimeters equal one centimeter, about 25 millimeters is one inch.
