27 million in scientific notation is 2.7 × 107.
To convert 27 million into scientific notation, you express the number as a product of a number between 1 and 10 and a power of ten. Since 27 million equals 27,000,000, writing it as 2.7 times 10 to the seventh power represents the same value more compactly.

Conversion Formula
Converting million to scientific notation uses the fact that one million equals 1,000,000 or 106. To convert any number in millions, multiply it by 106, then write the result as a number between 1 and 10 multiplied by a power of ten.
For example, 27 million equals 27 × 1,000,000 = 27,000,000. The next step is to write 27,000,000 in scientific notation:
- Move the decimal point 7 places left: 2.7
- Count the number of places moved: 7
- Scientific notation: 2.7 × 107
This works because 107 equals 10,000,000 and multiplying 2.7 by 10,000,000 gives 27,000,000.
Conversion Example
- Example 1: 15 million
- Start with 15 million = 15,000,000
- Move decimal 7 places left: 1.5
- Number of places moved: 7
- Scientific notation: 1.5 × 107
- Example 2: 3.2 million
- 3.2 million = 3,200,000
- Move decimal 6 places left: 3.2
- Since 3.2 is already between 1 and 10, exponent is 6
- Scientific notation: 3.2 × 106
- Example 3: 50 million
- 50 million = 50,000,000
- Move decimal 7 places left: 5.0
- Count 7 places moved
- Scientific notation: 5.0 × 107
- Example 4: 0.7 million
- 0.7 million = 700,000
- Move decimal 5 places left: 7.0
- Exponent is 5
- Scientific notation: 7.0 × 105

Conversion Definitions
Million: A million is a numerical value equal to one thousand thousands, represented as 1,000,000 or 106. It is used to express large quantities in counting, finance, science, and measurement. The million is a basic unit in the metric system for large scale numbers.
Scientific: Scientific notation is a way of expressing numbers as a product of a number between 1 and 10 and a power of ten. This notation simplifies working with very large or very small numbers by reducing digit counts and making calculations easier and clearer.
Conversion FAQs
Why is 27 million expressed as 2.7 × 10⁷ in scientific notation?
Because scientific notation requires a number between 1 and 10 multiplied by a power of 10, 27 million (27,000,000) is rewritten by shifting the decimal point 7 places left, turning 27 into 2.7, and multiplying by 10⁷ to compensate for the shift.
Can I convert million to scientific notation without using a calculator?
Yes, you can do it by understanding that 1 million equals 10⁶. So multiply your number in millions by 10⁶, then adjust the decimal to make the first part between 1 and 10. Counting how many places you moved the decimal gives you the exponent for 10.
Is scientific notation only for large numbers like millions?
No, scientific notation is also used for very small numbers, such as 0.00027, which would be 2.7 × 10⁻⁴. It helps to write both extremely large and tiny numbers in a simpler, compact form.
How do I read numbers written in scientific notation correctly?
You read the first part as a decimal number, then say “times ten raised to the power of” the exponent. For example, 2.7 × 10⁷ is “two point seven times ten to the seventh power,” meaning 2.7 multiplied by 10 million.
What happens if I convert a decimal million value like 0.5 million?
For 0.5 million, multiply by 10⁶ gives 500,000. Writing it in scientific notation, move the decimal 5 places left to get 5.0 × 10⁵. This shows smaller millions can have smaller exponents in scientific form.
