20 trillion converted to scientific notation is 2 × 1013.
To convert 20 trillion into scientific notation, you express the number as a product of a decimal number between 1 and 10, and a power of ten. Since trillion means 1012, 20 trillion equals 20 × 1012, which simplifies to 2 × 1013.

Conversion Formula
The formula to convert a value from trillion to scientific notation involves multiplying the trillion value by 10 to the power of 12. This is because one trillion is equal to 1,000,000,000,000 or 1012. So the formula is:
Scientific Notation = Trillion Value × 1012
Then, rewrite the result in the form of a number between 1 and 10 multiplied by a power of ten.
Example: Convert 20 trillion
- Multiply 20 × 1012 = 20,000,000,000,000
- Rewrite 20 as 2 × 10, so 20,000,000,000,000 = 2 × 10 × 1012
- Combine powers of 10: 2 × 101 + 12 = 2 × 1013
Conversion Example
- Convert 5 trillion:
- 5 × 1012 = 5,000,000,000,000
- 5 is between 1 and 10, so keep as is.
- Scientific notation is 5 × 1012.
- Convert 12 trillion:
- 12 × 1012 = 12,000,000,000,000
- Rewrite 12 as 1.2 × 10
- So, 1.2 × 10 × 1012 = 1.2 × 1013
- Convert 0.8 trillion:
- 0.8 × 1012 = 800,000,000,000
- 0.8 is less than 1, so keep 8 × 10-1
- Rewrite as 8 × 10-1 × 1012 = 8 × 1011
- Convert 30 trillion:
- 30 × 1012 = 30,000,000,000,000
- Rewrite 30 as 3 × 10
- Scientific notation is 3 × 1013

Conversion Definitions
Trillion: A trillion is a number equal to one thousand billion, or 1,000,000,000,000. It is represented as 10 to the power of 12 in scientific notation. Trillion is used for counting very large quantities in finance, science, and data measurement.
Scientific: Scientific notation is a way of expressing numbers as the product of a decimal number between 1 and 10 and a power of ten. It simplifies handling very large or very small numbers by compactly representing their scale through exponents.
Conversion FAQs
Why is 20 trillion written as 2 × 1013 and not 20 × 1012?
Although 20 × 1012 is mathematically correct, scientific notation requires the decimal part be between 1 and 10. Since 20 is larger than 10, you convert it to 2 × 10 and multiply the powers of ten, resulting in 2 × 1013. This format is standardized for clarity.
Does the scientific notation change when converting negative trillion values?
No, the process for negative numbers is the same, except the sign is kept negative. For example, -5 trillion becomes -5 × 1012. The magnitude conversion is identical, only the sign changes.
How precise is the scientific notation when converting trillions?
Scientific notation shows the scale of the number very precisely, but the decimal portion determines accuracy. For trillions, using one or two decimal places in the coefficient is common, but more digits can be added if more precise measurement is required.
Can scientific notation be used for numbers smaller than one trillion?
Yes, scientific notation works for any number. For example, 0.5 trillion is 5 × 1011. This method is helpful for very large or very small numbers, making them compact and easier to read or compute with.
What is the difference between scientific notation and exponential notation?
They are mostly the same in usage; both represent numbers as a base multiplied by 10 raised to an exponent. Scientific notation specifically requires the base number to be between 1 and 10, while exponential notation can be more flexible in form.
