This billion to trillion converter will help you quickly and easily convert numbers from billions to trillions and vice versa. Billions and trillions are very large numbers in the decimal number system. While we are often aware of their existence, we do not typically use them in our everyday lives.

You may use the calculator by entering the number in either the billion or trillion fields, and our tool will display the conversion automatically. If you wish to learn more beyond how to convert billions to trillions or how many zeroes there are in a billion and trillion, our calculator also allows you to display the values in scientific notation. To do this, you need to change the powers of 10 in the field labeled scientific notation.

## How many billions equal a trillion?

1000 billion (1,000,000,000,000) is 1 trillion.

Here are some interesting facts about billions:

• We use the symbols B, bn, or bil to represent billions.

• The most common abbreviation for the word billion is B.

• In scientific notation or standard form, we express 1 billion as 1×109.

## 1 trillion is equal to how many billion?

One trillion (1,000,000,000,000) is the equivalent of 1000 billion or 1 million millions.

• We use the symbols T or tn to represent trillion.

• The most common abbreviation is T.

• In standard form or scientific notation, we write 1 trillion as 1×1012.

Whatever abbreviation you use to represent these numbers, it is typical to choose only one and use it consistently.

## How many zeros are in a billion and trillion?

If you have ever wondered how many zeroes are in a billion or trillion, we have displayed the larger numbers on the place value chart below. Not only will this help you to visualize them, but you can also see what number comes after a trillion.

Additionally, if you are working with other large numbers, be sure to check out our billion to million converter. If you are interested in the Indian place-value system, we also have a crore to million converter available.

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.

## 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.

## 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.

## 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×10b), you should follow the below procedure:

1. 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).

2. This number at the front represents a. In the above example, a is 3.

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.

4. Because the decimal place has moved to the left, b is positive.

5. When we write 3,670,000,000 in standard form, the answer is 3.67×109.

6. 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:

1. 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.

2. 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.

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