- order of magnitude
- a logarithmic unit used to compare the sizes of quantities. Two quantities differ by one order of magnitude if one is 10 times the other, by two orders of magnitude if one is 10·10 = 100 times the other, and so on. Thus a difference of n orders of magnitude means the larger quantity is 10n times the smaller one.
