[Maths Class Notes] on Trillion Pdf for Exam

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 = 5×0.0001 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  = 9×0.0001 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  = 9×1000 or 9000 billion

Therefore, 9 trillion is equal to 9000 billion.
