How Many Zeros in a Million Billion Trillion? (List, Chart, Conversions) - BYJUS (2024)

One million is equal to thousand thousands. In one million, we have 1 followed by 6 zeros, that is, 1, 000, 000 and it can be written as \(10^6 \)(ten to the sixth power). It takes around 11 and a half days to complete one million seconds.

1 million = 1, 000, 000

One billion is equal to a thousand millions. 1 billion has 1 followed by 9 zeros, that is, 1, 000, 000, 000 and it is represented as \(10^9 \)(ten to the ninth power). One billion seconds is about 32 years.

1 billion = 1, 000, 000, 000

Now, let’s move on to 1 trillion.

One trillion equals a thousand billions, or million millions. 1 trillion consists of 1 followed by 12 zeros, that is, 1, 000, 000,000, 000 and can be written as \(10^{12} \)(ten to the twelfth power). It takes about 32,000 years to finish 1 trillion seconds.

1 trillion = 1, 000, 000, 000, 000

[Note: The values which are greater than a trillion are called Quadrillion \((10^{15}) \)and Quintillion \((10^{18}) \).]

The value of each digit in a number can be determined using a place value chart. In order to determine the value of the various digits in a number, we need to place the given number into the place value chart so that the place value of each digit can be observed. The image shows us how a place value chart looks like.

Although the numbers millions and billions are larger, a basic multiplication operation is all we need to convert them. So, to convert a million to a billion we just have to divide the given number by 1000 billion.

Million to billion = \(\frac{(given ~value ~in~million)}{1000} \)billion

[Note: Similarly, we can even convert a billion to a million by multiplying the billion value by 1000.]

We will now try converting millions to trillions. It may sound a bit challenging. However, we need to do the similar thing that we do for a million to billion conversion. Here, instead of dividing by 1000, we divide the given number with 1000000.

Million to trillion = \(\frac{(given ~value ~in~million)}{1000000} \)trillion

[Note: By multiplying the million value by 1000000, we can convert a trillion to a million.]

So now, we will turn a billion to a trillion by dividing the given billion number by 1000.

Billion to trillion = \(\frac{(given ~value ~in~billion)}{1000} \)trillion

[Note: Also, by multiplying the trillion value by 1000, we can convert a trillion to a billion.]

Example 1:

The annual income of Temperate Springs, a company that makes carpets, is $2 million. Can you find how many billions it equals to?

Solution:

Given, the annual income of the company is $2 million.

We know that one billion is equivalent to a thousand million.

Then, by using the million to billion formula we can write,

Million to billion = \(\frac{(given ~value ~in~million)}{1000} \)billion

= \(\frac{2}{1000} \)billion

= 0.002 billion

Hence, the annual income of the Temperate Springs is $0.002 billion.

Example 2:

According to a study, astronomers stated that the Milky Way has 200 billion stars. Then, what would be the count of stars in trillions?

Solution:

As mentioned, the Milky Way has 200 billion stars.

In order to convert it into trillions we can directly use the billion to trillion conversion formula.

That is,

Billion to trillion = \(\frac{(given ~value ~in~billion)}{1000} \)trillion

= \(\frac{200}{1000} \)trillion

= 0.2 trillion

Therefore, the number of stars in the Milky Way is 0.2 trillion.

Example 3:

How many millions is 3 trillions?

Solution:

We already know that one trillion is equivalent to 1 million millions.

By using the formula,

Trillions to millions = (Given value in trillions \(\times\) 1000000) millions

= 3 \(\times\) 1000000 millions

= 3000000 millions

Thus, 3 trillions = 3, 000, 000 millions.
