225 million in scientific notation is 2.25 × 108.
To convert 225 million into scientific notation, we express it as a number between 1 and 10 multiplied by a power of ten. Since 225 million equals 225,000,000, shifting the decimal point eight places to the left gives 2.25 × 108.

Conversion Formula
To convert a value from million to scientific notation, multiply the number by 1,000,000 (which is 106) and then express the result in the form of a × 10n, where a is a decimal number between 1 and 10, and n is an integer.
It works because one million equals 106, so multiplying by million shifts the decimal six places to the right. Then you adjust the decimal to fit scientific notation rules.
Example:
- Start with 225 million = 225,000,000
- Rewrite as 2.25 × 100,000,000
- Since 100,000,000 = 108, final form is 2.25 × 108
Conversion Example
- Example: 300 million
- 300 million equals 300,000,000
- Move decimal 8 places left: 3.00
- Multiply by 108 → 3.00 × 108
- Example: 150 million
- 150 million is 150,000,000
- Decimal shift: 1.5
- Multiply by 108 to get 1.5 × 108
- Example: 75 million
- 75 million equals 75,000,000
- Decimal shift: 7.5
- Multiply by 107 since 7.5 is less than 10 → 7.5 × 107
- Example: 12.5 million
- 12.5 million is 12,500,000
- Decimal shift: 1.25
- Multiply by 107 → 1.25 × 107
- Example: 500 million
- 500 million equals 500,000,000
- Decimal shift: 5.00
- Multiply by 108 → 5.00 × 108

Conversion Definitions
Million: A million is a number equal to one thousand thousands, written numerically as 1,000,000. It represents a large quantity and is commonly used in measuring population, money, or other countable items. One million is equivalent to 106 in exponential form.
Scientific: Scientific notation is a way of expressing numbers as a product of a decimal number between 1 and 10 and a power of ten. It simplifies writing very large or very small numbers by using exponents to indicate how many times the decimal point moves.
Conversion FAQs
Why is 225 million written as 2.25 × 108 in scientific notation?
225 million equals 225,000,000. In scientific notation, you write numbers as a decimal between 1 and 10 multiplied by 10 raised to a power. Moving the decimal 8 places left converts 225 million to 2.25 × 108. The exponent 8 counts how many places the decimal shifts.
Can scientific notation have different exponents for the same million value?
Scientific notation requires the decimal to be between 1 and 10, so the exponent depends on shifting the decimal point accordingly. For 225 million, the correct exponent is 8. Using a different exponent would not follow the standard scientific notation rules.
How to handle decimal million values in scientific notation?
Decimal million values like 12.5 million convert by multiplying 12.5 by 1,000,000 to get 12,500,000. Then, rewrite as 1.25 × 107, shifting the decimal 7 places. The exponent adjusts to keep the decimal between 1 and 10.
Is the conversion formula different for billion or thousand?
Yes, the formula changes with the scale. For billion, multiply by 109, for thousand by 103. Each unit has its own power of ten, so scientific notation adjusts accordingly to represent the number correctly.
Does the conversion tool round the scientific notation result?
The tool multiplies the input million value by 1,000,000 and shows the result with four decimal places. It does not display the number in scientific notation format but gives the full numeric value rounded for readability.
