# Can an order of magnitude be negative?

## Can an order of magnitude be negative?

In one meaning, it is a number’s nearest power of 10. For example, 9.9×102 is much closer to 103 than to 102 , so we say that the order of magnitude is 3 . By the same argument, 9.9×10−3 is closer to 10−2 than to 10−3 , so we say that the order is −3 .

What do u mean by order of magnitude?

An order of magnitude is the class of scale of any amount in which each class contains values of a fixed ratio to the class preceding it. The order of magnitude of a physical quantity is its magnitude in powers of ten when the physical quantity is expressed in powers of ten with one digit to the left of the decimal.

What is a full order of magnitude?

An order of magnitude is an exponential change of plus-or-minus 1 in the value of a quantity or unit. The term is generally used in conjunction with power-of-10 scientific notation. Thus, 23.15 is one order of magnitude smaller than 231.5, which in turn is one order of magnitude smaller than 2315.
