Definitions for "Order of Magnitude"
Two quantities are of the same order of magnitude if one is less than 10 times as large as the other. Each increase of one power of 10 is an increase in magnitude of 1. For example, 106 is 4 orders of magnitude above 102.
An amount equal to 10 times a given value; thus if some quantity was 10 times as great as another quantity, it would be an order of magnitude greater; if 100 times as great, it would be larger by two orders of magnitude
The difference in two values measured by their logarithms. The quantity 100 (log=2.0) is an order of magnitude larger than the quantity 10 (log=1.0).
A term used in science to indicate a range of values representing numbers, dimensions, distances, etc., which start at any given value and ends at 10 times that value.
