Size of a value by approximate factors of 10.

Examples:

• the order of magnitude of 12 is

• the order of magnitude of 170 is

• a kilometer (1000 meters) is three orders of magnitude greater than a meter.

Can also be used to mean "very much" bigger or smaller.

Example: "Sam's tennis game is an order of magnitude better this year"

Below are examples of the order of magnitude of lengths:

Examples:

• the order of magnitude of 12 is

**1**because it is around 10 in size.• the order of magnitude of 170 is

**2**because it is around 100 in size.• a kilometer (1000 meters) is three orders of magnitude greater than a meter.

Can also be used to mean "very much" bigger or smaller.

Example: "Sam's tennis game is an order of magnitude better this year"

Below are examples of the order of magnitude of lengths:
