🔢 Million to Billion Converter
Convert between millions and billions using the standard short-scale numbering system used in the U.S., UK, and most international finance.
Converting millions to billions
In the short-scale numbering system used in the United States, United Kingdom, and most international finance and media, 1 billion equals 1,000 million (1,000,000,000). This calculator uses that standard relationship to convert between the two in either direction.
To convert millions to billions, divide by 1,000. To convert billions to millions, multiply by 1,000. The raw underlying number is also shown for clarity, since large figures can otherwise be easy to misread.
Note that some countries historically used the long-scale system, where 1 billion equals 1 million million (10^12), though this is now uncommon in modern financial reporting. This tool uses the short-scale definition and is intended for general reference and educational purposes.
