200 million in scientific notation is written as 2.0 × 108.
To convert 200 million into scientific notation, you express it as a number between 1 and 10 multiplied by a power of ten. Since 200 million equals 200,000,000, shifting the decimal point 8 places to the left results in 2.0 multiplied by 10 to the power of 8.

Conversion Formula
The conversion from million to scientific notation involves multiplying the given value by 1,000,000 (which is 106), then expressing the product in the form a × 10n, where a is a number between 1 and 10, and n is an integer.
Why this works? Because 1 million equals 106, so any “million” value times 1,000,000 gives the actual number. Then, scientific notation rewrites that number by placing the decimal after the first digit and counting how many places it moved.
Example:
- Start with 200 million = 200 × 1,000,000 = 200,000,000
- Rewrite 200,000,000 as 2.00 × 100,000,000
- Since 100,000,000 = 108, the scientific notation is 2.00 × 108
Conversion Example
- Example: 150 million
- 150 × 1,000,000 = 150,000,000
- Rewrite as 1.50 × 100,000,000
- Scientific notation: 1.50 × 108
- Example: 75 million
- 75 × 1,000,000 = 75,000,000
- Rewrite as 7.5 × 10,000,000
- Scientific notation: 7.5 × 107
- Example: 320 million
- 320 × 1,000,000 = 320,000,000
- Rewrite as 3.20 × 100,000,000
- Scientific notation: 3.20 × 108
- Example: 500 million
- 500 × 1,000,000 = 500,000,000
- Rewrite as 5.00 × 100,000,000
- Scientific notation: 5.00 × 108

Conversion Definitions
Million: A million is a numerical value equal to one thousand thousands, or 1,000,000 (106). It is often used to quantify large amounts, like population or money, and it represents a base unit in the metric numbering system for large numbers.
Scientific: Scientific notation is a way of representing numbers as a product of a number between 1 and 10 and a power of ten. It simplifies writing very large or very small numbers by showing the order of magnitude explicitly, making calculations and comparisons easier.
Conversion FAQs
Why is multiplying by 1,000,000 necessary when converting million to scientific notation?
Multiplying by 1,000,000 converts the value from millions to its actual number. Since “million” means 106, the multiplication adjusts the scale to reflect the full numeric value before rewriting it in scientific notation.
Can I write 200 million as 20 × 107 instead of 2 × 108?
Technically yes, but scientific notation requires the coefficient to be between 1 and 10, so 20 × 107 is not valid scientific notation. You should rewrite it as 2.0 × 108.
Does the number of decimal places in the coefficient affect the scientific notation?
The coefficient in scientific notation can have decimal places based on the precision needed. For example, 2.0 × 108 and 2.00 × 108 represent the same number but the latter shows more precision.
Is scientific notation only for large numbers like 200 million?
No, scientific notation is used for both very large and very small numbers. It helps in expressing tiny values like 0.000003 as 3.0 × 10-6, making them easier to work with.
How do I convert scientific notation back to a regular number?
To convert scientific notation to a regular number, multiply the coefficient by 10 raised to the given exponent. For example, 2.0 × 108 equals 2.0 times 100,000,000, which is 200,000,000.
