One billion is equal to 1,000 million. In other words, one billion is a thousand times larger than one million. Therefore, it takes 1,000 millions or one thousand million to make a billion.

## How many millions make a billion?

In terms of whole numbers, one billion is equal to 1,000 million. In other words, one billion is a thousand times larger than one million.

To understand this better, let’s break down the numbers.

- One million is written as 1,000,000. It is the number that comes after 999,999 and before 1,000,001. One million is equivalent to 1,000 thousands, or 1,000 x 1,000.
- One billion is written as 1,000,000,000. It is the number that comes after 999,999,999 and before 1,000,000,001. One billion is equivalent to 1,000 millions, or 1,000 x 1,000,000.

Therefore, it takes 1,000 millions or one thousand million to make a billion. This means that if you have one billion dollars, you have one thousand million dollars.

In some countries, such as the United Kingdom, a billion traditionally referred to a million million (1,000,000,000,000), rather than a thousand million (1,000,000,000) as used in the United States and other countries. However, the usage of a billion as a thousand million is becoming more common worldwide.
