One billion years may be called an eon in astronomy or geology.

Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000). However, this is no longer common, and the word has been used to mean one thousand million (1,000,000,000) for several decades.[4]

The term milliard can also be used to refer to 1,000,000,000; whereas "milliard" is rarely used in English,[5] variations on this name often appear in other languages.

In the South Asian numbering system, it is known as 100 crore or 1 arab.
