How to Convert Millions, Billions, and Trillions Easily
A trillion is a number with two different definitions.
1 million million i.e.1,000,000,000,000 or 10¹² is defined as the short-scale trillion. This is the meaning of trillion in both American and British English.
1,000,000,000,000,000,000 or 10¹⁸ is larger than the short scale trillion.The long scale trillion is one million times larger than the short scale trillion. This is the historical meaning of trillion in English and presently used in different non-speaking English countries where trillion and billion maintain their long-scale definitions.
In the American system, 1 trillion equals a thousand thousand millions, or 10 to the 12th, whereas In the British system, 1 trillion equals a million million millions, or 10 to the 18th . Although, The American system has been common in both the United States and Britain, and the American definitions are gaining acceptance nowadays. However, the historical geographic distinctions are also needed to be considered. This has aided in the constitution of “trillion” for the purpose of development of standardization of terminology for representing large numbers in simpler and more logical form than the American one.
How Much is One Trillion?
One trillion dollars is equivalent to a thousand billion, or million dollars multiplied by millions. A trillion is a 1 with 12 zeros after it, represented as 1,000,000,000,000 or 10¹².
A million can be denoted as 106, or 1,000,000, and a billion can be denoted as 1 thousand million, or 1,000,000,000 (109).
The word billion has been derived from the French word bi- (“two”) + -illion; i.e. a million million. It was first originated by Jehan Adam in 1475 as by-million and later it was rendered as byllion by Nicolas Chuquet in 1484.
The word Million originated from the Italian milione, from the Latin mille + the augmentative suffix -one.
For instance, A billion seconds would amount to 32 years, and a trillion seconds would amount to 32,000 years.
How Many Billions Make a Trillion?
The answer to the question “ How Many Billions Make A Trillion” depends on the place where you live.
(In the US, Modern British and Australian, short scale) , one thousand billion makes one trillion, represented as 1,000,000,000,000 or 10¹².
(In Older British, Australian, long scale), one million billion makes one trillion, represented as 1,000,000,000,000,000,000 or 10¹⁸.
A British trillion used to be equivalent to one million American trillions, but now both are mostly similar.
How Many Millions in One Trillion?
One trillion dollars is defined as one million dollars multiplied by a million, or one million million makes one trillion.
Examples:
Earth is about a trillion meters far from the Moon
The Galaxy contains about a trillion stars
There are around 3 trillion trees on Earth
The human body contains around 90 trillion bacteria and around 100 trillion cells.
There are about 3 trillion different fishes in the ocean
A terameter is a trillion meters, where the prefix "tera-" means a trillion.
Suppose a cube is made of a million smaller cubes. If each of the small cubes is worth a million dollars, then the whole cube is worth a trillion dollars.
How to Convert Million to Trillion?
The formula to convert million to trillion is:
1 Million = 1E - 06 Trillion
Accordingly, we can convert millions to trillions by multiplying the value given in million by 1.0E - 06. For example, to convert 5 million to trillions, the calculation is
5 Million = 5 1.0E - 06 or 5E - 6 trillion
Therefore, 5 million is equal to 5.0E - 6 trillion.
How to Convert Trillion to Million?
The formula to convert trillion to million:
1 Trillion = 1000000 Millions
Accordingly, we can convert a trillion to a million by multiplying the value given in trillion by 1000000. For example, to convert 5 trillion to a million, the calculation is
5 Trillion = 5 x1000000 or 5000000 million
Therefore, 5 trillion equals 5000000 million.
How to Convert Billion to Trillion?
The formula to convert billion to trillion is:
1 Billion = 0.0001 Trillion
Accordingly, we can convert a billion to a trillion by multiplying the value given in a billion by 0.0001. For example, to convert 5 billion to trillion, the calculation is
5 Billion = 5x0.0001 or 0.0005 trillion
Therefore, 5 billion is equal to 0.0005 trillion.
How to Convert Trillion to Billion?
The formula to convert trillion to billion is:
1 trillion = 1000 billion
Accordingly, we can convert trillion to billion by multiplying the value given in trillion by 1000. For example, to convert 5 trillion to a billion, the calculation is
5 Trillion = 5 1000 or 5000 billion
Therefore, 5 trillion is equal to 5000 billion.

Solved Examples
1. Convert 7 Million to Trillions
The formula to convert million to trillion is:
1 Million = 1E - 06 Trillion
Accordingly,
7 Million = 7 1E - 06 = 7.0E - 6 Trillion
Therefore, 7 million is equal to 7.0E - 6 trillion
2. Convert 7 Trillion to Million
The formula to convert trillions to millions:
1 Trillion = 1000000 Millions
Accordingly,
7 Trillions = 7 x1000000 or 7000000 million
Therefore, 7 trillion is equal to 7000000 million.
3. Convert 9 Billions to Trillions
The formula to convert billion to trillion is:
1 Billion = 0.0001 Trillion
Accordingly,
9 Billions = 9x0.0001 or 0.0009 trillion
Therefore, 9 billion is equal to 0.0009 trillion
4. Convert 9 Trillion to Billions
The formula to convert trillion to billion is:
1 trillion = 1000 billion
Accordingly,
9 Trillions = 9x1000 or 9000 billion
Therefore, 9 trillion is equal to 9000 billion.

FAQs on What Is a Trillion? Definition & Key Maths Facts
1. How many billions are in a trillion?
There are 1,000 billions in a trillion. In mathematics, one billion is $1,000,000,000$ (one thousand million), so a trillion is $1,000 imes 1,000,000,000 = 1,000,000,000,000$. This mathematical concept is crucial for understanding large numbers, which students often encounter in subjects like science and economics. At Vedantu, our expert tutors explain such topics using engaging examples and real-life applications to build a strong numerical foundation.
2. What is a trillion called?
A trillion is the name given to the number 1,000,000,000,000, which is one million million or $10^{12}$. In the Indian numbering system, this equivalent is referred to as one lakh crore. Understanding such large numbers is important in topics like statistics and business mathematics, which are regularly covered in Vedantu’s interactive online classes.
3. How much is 1 trillion?
1 trillion is equal to $1,000,000,000,000$, or $10^{12}$ (one followed by twelve zeros). This is equivalent to
- 1,000 billions
- 1,000,000 millions
- One lakh crore (in India)
4. Are there any trillionaires?
As of now, there are no individual trillionaires in the world. A trillionaire is a person whose net worth is at least one trillion dollars ($1,000,000,000,000$). While some companies reach trillion-dollar valuations, no single person has yet achieved this milestone. Information about large numbers and financial terminology is often included in Vedantu’s math and economics syllabi to help students stay updated with real-world facts.
