# Trillion      ## What is the Meaning of Trillion?

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.

### Other Large Numbers

• Million=1,000,000

• Billion=1,000,000,000

• Trillion=1,000,000,000,000

• Quintillion=1,000,000,000,000,000,000

• Sextillion=1,000,000,000,000,000,000,000,000.

• Nonillion=1,000,000,000,000,000,000,000,000,000,000

• CENTILLION=1 followed by 303 zeros

### 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 Trillion

1. How long will it take to count 1 trillion dollars?

If you count one dollar per second, it would take 31688 years to count one trillion dollars. A trillion equals a 1,000 billion, and a billion is a thousand million. There are 31,536,000 seconds in a 365 day year, and 1 trillion divided by 31,536,000 is approximately 31,688. On this basis, the estimate of over 31,000 years to count to one trillion has been considered. It is based on an assumption that an individual is counting 1 number each second.

2. How many zeros make one million, one billion, and one trillion?

Zero plays an important role as you count larger numbers. As the number gets larger, more zeroes are needed. As you know,

• 1 thousand thousand makes one million, and one thousand has 3 zeros. Accordingly, one million has 6 zeros and is represented as 1,000,000.

• 1 billion is one thousand million. One billion is a 1 followed by 9 zeros and represented as 1,000,000,000.

• One trillion is a  thousand billion or equal to a million million. One million is a 1 followed by 12 zeros and represented as 1,000,000,000,000.

3. What is an estimate of the time to count to one trillion?

It is very difficult to count all exceptions for larger numbers. There are many more numbers from 100 billion to 1 trillion in comparison to numbers from 1 to 100 billion. (approximately 9 times). By considering numbers from 100 billion to 1 trillion, 90% of all the numbers from 1 through 1 trillion can be covered. Most numbers up to 1 trillion take 19 seconds to say: numbers like 832, 521,432,987. It has been estimated that it would take approximately 542,241 years to count to 1 trillion. As we know, there are  31,536,000 seconds in a 365 day year. Dividing one trillion by 31,536,000 is approximately 31,710.
