As you can see from the table above, 1 million has six zeroes, 1 billion has nine zeroes, one trillion has twelve zeroes, and one quadrillion has 15 zeroes.

4. How to convert billion to trillion

1000 billion is the equivalent of 1 trillion.

To convert billion to trillion, we use the formula below:

T = (B/1000)

So if we were to convert 5 billion to trillion, this would be:

T = (5/1000) = 0.005 × T

In the standard form, we would represent 0.005 × T as 5 × 10⁹.

5. How to convert trillion to billion

To convert billion to trillion, we multiply the trillions by 1000:

B = (T × 1000)

For example:

B = (20 × 1000) = 20,000 × B

In Standard form, we would represent 20 × T (20,000,000,000,000) as 2×10¹³.

6. How to convert numbers to their standard form

When we write numbers in scientific notation, we usually use the powers of ten to show how big or small the number is.

To represent 3,670,000,000, a value greater than or equal to one, in standard form (a×10^b), you should follow the below procedure:

First, move the decimal place to the left until only one number is at the front. The number cannot be 0 (e.g., 3.67).
This number at the front represents a. In the above example, a is 3.
Next, count the number of places by which you moved the decimal point. The number of decimal places represents b. In the above example, b is 9.
Because the decimal place has moved to the left, b is positive.
When we write 3,670,000,000 in standard form, the answer is 3.67×10⁹.
You can repeat the above steps for negative numbers, but they must be equal to or lower than minus one. You can also use our billion to trillion converter to obtain the same answer.

We use the same formula above to represent a number in its standard form whose absolute value is less than one. However, the process is a little different. Here are the steps:

First, move the decimal place to the right until the number in front of the decimal is greater than 0. For example, the number we are changing to the standard form is 0.0000008956. When we move the decimal place, a will be 8. The number will look like this 8.956.
Next, we need to count the number of places that the decimal has moved. This number represents b (b = -7).

Note: Because we moved the decimal place to the right, b is negative.

Next, rewrite the formula using the numbers. In the standard form, the answer is 8.956 x 10^-7.

In terms of billions, one trillion is equal to 1,000 billion.

What's after trillions?

After trillions, we have the term quadrillions, which indicate one thousand millions of millions, denoted as 1,000,000,000,000,000 (or 10¹⁵). One quadrillion is equivalent to 1,000 trillion or 1,000,000 billion.

How do I convert 1.9 billion in trillions?

You can easily determine this conversion by following these steps:

Use the conversion factor between billions and trillions:

1 billion = 0.001 trillions

or

1000 billions = 1 trillion.
Divide the number 1.9 billion by 1000:

1.9 billion (1 trillion / 1000 billion)

1.9 billion = 0.0019 trillions.
That's it! Now you have your result.

Is 500 billion half a trillion?

Yes. Given that 1,000 billion are equivalent to 1 trillion, it follows that half a trillion is equal to 500 billion. You can see the relationship in the following calculations:

1,000 billion = 1 trillion.

1,000 billion / 2 = 1 trillion / 2.

500 billion = 0.5 trillion.
