Definition

1. Noun:
   • The cardinal number equal to 1,000,000,000: "one thousand million" is a numerical term representing the quantity of one billion (1,000,000,000). It is composed of the digits one, followed by nine zeros.

Usage

• This term is used to specify a very large quantity or amount. It is a precise numerical expression.

Advanced Usage

• Historical/Long Scale Usage: In some historical or regional contexts (e.g., traditional British English), "one thousand million" was used to avoid ambiguity with the now-archaic "billion," which could mean a million million (1,000,000,000,000). In modern international and scientific English, this distinction is largely obsolete.
