20 trillion in scientific notation is 2 × 1013.
This means that the number 20 trillion can be written as 2 times 10 raised to the power of 13. Scientific notation expresses large numbers more compactly by using powers of ten, making them easier to read and work with.

Conversion Formula
To convert a value from trillion to scientific notation, multiply the number by 10 raised to the 12th power. This is because one trillion equals 1,000,000,000,000, which is 1012. Scientific notation represents numbers as a product of a decimal number between 1 and 10, and a power of ten.
For example, converting 20 trillion:
- Start with 20 trillion = 20 × 1,000,000,000,000
- Rewrite 1,000,000,000,000 as 1012
- So, 20 trillion = 20 × 1012
- Express 20 as 2 × 10 to adjust for scientific notation: 20 = 2 × 10
- Combine powers of ten: (2 × 10) × 1012 = 2 × 1013
- Final scientific notation: 2 × 1013
Conversion Example
- Example: 5 trillion
- 5 trillion = 5 × 1012
- 5 is already between 1 and 10, so scientific notation is 5 × 1012
- Example: 50 trillion
- 50 trillion = 50 × 1012
- Convert 50 to 5 × 10, so 50 × 1012 = 5 × 10 × 1012
- Combine powers: 5 × 1013
- Example: 0.3 trillion
- 0.3 trillion = 0.3 × 1012
- 0.3 is between 1 and 10? No, so move decimal: 3 × 10-1 × 1012
- Combine exponents: 3 × 1011
- Example: 123 trillion
- 123 trillion = 123 × 1012
- Rewrite 123 as 1.23 × 102
- Multiply: 1.23 × 102 × 1012 = 1.23 × 1014

Conversion Definitions
Trillion: A trillion is a numerical value equal to one million million, represented as 1,000,000,000,000 or 10 to the 12th power. It is commonly used in finance, science, and economics to denote very large quantities or amounts in counting or measuring.
Scientific: Scientific notation is a method of writing numbers that expresses them as a product of a decimal number between 1 and 10, and a power of ten. This format simplifies handling extremely large or small numbers in calculations and data representation.
Conversion FAQs
Can I convert negative trillions into scientific notation the same way?
Yes, negative values in trillions convert just like positive ones. The negative sign remains, and you multiply the absolute value by 1012. For example, -3 trillion becomes -3 × 1012. The process does not change due to the sign.
Why does 20 trillion become 2 × 1013 instead of 20 × 1012?
Scientific notation requires the decimal part to be between 1 and 10, so 20 is adjusted to 2 × 10. Then, the powers of ten add up: 10 (from 20) plus 1012 equals 1013. Writing 20 × 1012 is correct but not in proper scientific form.
Is scientific notation always easier to work with for trillions?
Scientific notation makes it easier to write, read, and perform calculations with very large numbers like trillions. However, depending on the context, using the full number or words may be clearer for some audiences, especially when precision isn’t crucial.
How do I convert scientific notation back to trillion?
To go back, divide the number by 1012. For example, 2 × 1013 divided by 1012 equals 20 trillion. This reverses the earlier multiplication and gets you the original value in trillions.
Does the conversion change if the number is in billions or millions instead of trillions?
Yes, the base power of ten changes. Billions correspond to 109, millions to 106, and trillions to 1012. So conversion requires multiplying by the correct power, adjusting the scientific notation accordingly.
