Order Of Magnitude
An order of magnitude is the approximation of a comparison. This system of classification is determined by size, quantity, quality, and other factors. For instance, objects which are arranged from an ascending order of magnitude would most probably be displayed from smallest to biggest.
Moreover, order of magnitude is often associated with scientific notation. This is usually specified as 10 to the nth power with the “n” as the order of magnitude. It means that a level is 10 times more than the previous one. Hence, 1000 has three orders of magnitude since 10 to the third power is 1000.
