coterminous

Use the word coterminous to describe things that are equal in scope. If an earthquake in Australia was coterminous with the earthquake in China, that means it caused the same amount of destruction.

The adjective coterminous derives from the Latin word conterminus, meaning "bordering upon, having a common boundary." When something is coterminous, it has the same boundaries, or is of equal extent or length of time as something else. The expansion of the American Old West was coterminous with the expansion of the Great American Frontier. Your mayor's term in office might be conterminous with increased access to social services.
