order of magnitude

Noun

 * 1)  The class of scale or magnitude of any amount, where each class contains values of a fixed ratio (most often 10) to the class preceding it.
 * 2) * 2011, Enrico Fermi, Wikisource (translator), Concerning a Contradiction between the Electrodynamic and Relativistic Theory of Electromagnetic Mass, 1922, Enrico Fermi, Über einen Widerspruch zwischen der elektrodynamischen und relativistischen Theorie der elektromagnetischen Masse, Physikalische Zeitschrift, v 23, pp 340-344,
 * However, we notice that although this contraction is of order of magnitude $$v^{2}:c^{2}$$, it changes the most important terms of electromagnetic mass, i.e, the rest mass.
