How Many Millions are in a Billion?

There are 1000 millions in one billion.

The relationship between millions and billions is expressed numerically as follows:

1 billion = 1,000 million

Mathematically:

1,000,000,000 / 1,000,000 = 1,000

A million is a numerical value representing 1,000,000 (one million). This figure is often represented as 10⁶ in scientific notation. It can be visualised as a one followed by six zeros: 1,000,000. In spoken language, it’s commonly referred to as “a million“.

On the other hand, a billion represents 1,000,000,000 (one billion) or 10⁹ in scientific notation. It is a vastly larger number than a million, being equivalent to one thousand millions. A billion is represented as a one followed by nine zeros: 1,000,000,000.

To illustrate the relationship, consider converting a billion into millions. Since a billion is equivalent to one thousand million, you can divide a billion by a million to find the answer.

Therefore, there are 1,000 millions in 1 billion.
