In standard modern English and global finance, a billion is 1,000,000,000 (one followed by nine zeros). Because a million is 1,000,000 (one followed by six zeros), multiplying a million by 1,000 gives you one billion.

Quick Breakdown

• Standard Short Scale. Used in the US, the UK, and most English-speaking regions, each new number name is 1,000 times larger than the last, making 1 billion equal to 1,000 million.
• Historical Long Scale. Historically used in Britain and still common in some non-English European languages, a billion meant a million millions (1,000,000,000,000). In those languages, 1,000 million is called a milliard.
• Easy Conversion. To convert billions to millions, multiply by 1,000 (for example, 2.5 billion equals 2,500 million). To convert millions to billions, divide by 1,000 (for example, 500 million equals 0.5 billion).
