How Many Millions Make a Billion?

Answer: 1 billion = 1,000 million

Yes, it’s that simple! The answer to how many millions make a billion is one thousand million. In number form, 1 billion is written as 1,000,000,000, and 1 million is 1,000,000. If you divide 1,000,000,000 by 1,000,000, you get 1,000.

Let’s Break It Down with Place Value

Here’s how place value works with big numbers:

Number	Name	Number of Zeros
1000	Thousand	3
1,000,000	Million	6
1,000,000,000	Billion	9

Each time you move to the next level, you multiply by 1,000. That’s why:

• 1 million = 1,000 thousands
• 1 billion = 1,000 millions

Why the Relationship between Millions and Billions is Important to Know

Understanding the relationship between millions and billions is super useful—not just in maths class, but also in real life. You will hear these big numbers in news reports, when people talk about money, populations, or even distances in space. For example:

• India’s population is over 1.4 billion, that’s 1,400 million people!
• Big companies like Apple and Amazon earn billions of dollars every year.
• NASA measures distances in space using millions and billions of kilometers.
• Knowing how to convert between millions and billions helps you make sense of all this.

Fun Fact

In some countries, especially in Europe, people used to follow a different number system where:

1 billion = 1 million million (i.e. 1,000,000,000,000)

But today, most of the world uses the short scale system, where:

1 billion = 1,000 million (i.e. 1,000,000,000)

So for your CBSE Class 6 Maths syllabus, always remember: 1 billion = 1,000 million.

Quick Trick to Remember

Think of “bi” in billion as meaning “two” – like in bicycle (2 wheels).

So, billion = 1 with 9 zeros, which is 3 sets of 3 zeros.

And million = 1 with 6 zeros, which is 2 sets of 3 zeros.

So: 1 billion = 1,000 million. Easy, right?
